With noticeable delay comes part three of the xeriscaping series, today we will be discussing ornamental xeriscaping.
Ornamental xeriscaping is exactly what most think of when the word xeriscaping comes to mind. While ornamental landscapes have their inherent aesthetic value they also can play a further functional role towards conservation. It is already well understood that the placement of deciduous trees can reduce heating and cooling bills of a household but little beyond the obvious is stated of the bill-reducing effects of a xeriscaped garden. Generally it is noted that xeriscaped gardens reduce your watering bill because they need reduced amounts of irrigation. What is not known is that with the right placement and plant selection xeriscaped gardens can also act as a effective windbreak to reduce the effects of either hot or cold wind and may serve as a protective layer for more sensitive plants or as a buffer zone to augment a protective layer of deciduous trees. Additionally certain xeriscape-compatible can act as a living mulch which in turn counters erosion of topsoil and can provide an attractive weed-block saving you time, money and reduce the need for fertilizers and pesticides. Some good plants for this use include Agave, Euphorbia, Ice Plant, Portulaca, Prickly Pear, Ornamental Sage, Sedum and, Yucca.
Agave
Most often agave is seen in the southeast as a perennial whereas up north it's treated as if it is a tropical. The most common variety is Agave americana which is slow growing but thankfully is quite rugged and can form an attractive centerpiece when paired with a living mulch.
Euphorbia
Best known for the Poinsettia, the euphorbia family has a number of perennial members that make for interesting color and shape contrasts for a xeriscaped garden. While generally not very long-lived as far as landscaping plants go it does make a striking addition to a otherwise monotone garden.
Ice Plant
Ice plants are an attractive flowering plant to consider for the xeriscaping garden. The name Ice plant comes from the sparkling appearance of the leaves which at a distance makes the plant appear to be coated in a light frost. The flowers come in shades of pink, red and yellow and are daisy-like in appearance. Ice plants form a dense mound of foliage that can be used to contrast other darker hued foliage or to soften angular foliage on plants such as agave or yucca.
Portulaca
Commonly called Purselane, Portulaca is both edible but also drought tough. Purselane is known to form low mats of rich green foliage with red stems. As a primary advantage Purselane can endure drought and with a little water it produces large numbers of large flowers in hues of red, yellow, pink and orange all on an annual plant who may reseed.
Prickly Pear
To be specific I mean Opuntia humifusa, which is the only solidly hardy type for the south east. Thankfully you can get spineless varieties of prickly pear to make gardening easy. Otherwise if you want a impenetrable wall of spiny herbicide resistant cactus in a few short years prickly pear will be all that. The large yellow or pink flowers are borne in sprin or early summer and are followed by bright red fruits in fall. Established stands can occupy entire hillsides and grow up to three feet tall.
Ornamental Sage
When you say sage most think of the annuals or the cooking spices but there are a large variety of sages that are both perennial and almost drought immune. The best of the group is Black Sage Salvia mellifera which looks like common sage but has a more pungent aroma. For note it is one of the three plants that make up sage brush and has interesting flowers as well.
Sedum
Sedum is commonly called stone crop, and is one of the most diverse perennial succulents one can buy at a garden center. Sedum is one of the most versatile landscaping plants because numerous foliage shapes, sizes and colors can be had and it's flower stalks
Yucca
Yucca is about as tough as xeriscaping plants come. Commonly called Spanish Bayonet or Adam's needle. Overall most yucca will form a mound that resembles a Dracena or corn plant on steroids. The leaves do have fine serrations and the tips are spiked, which makes careful handling a must. Overall with time yucca can form a dense impenetrable barrier that with age will spread by rhizomes. Once mature a yucca will produce tall flower stalks covered in white or cream colored bell-shaped flowers.
Next is part four of the xeriscaping series which covers naturalized xeriscaping which will be posted shortly.

Xeriscaping Part II: Agricultural Xeriscaping
Xeriscaping is generally thought of as an ornamental garden concept, which is fine since the majority of the time it is. With the effects of climate change, it is crucial to find a way to feed ourselves and yet not use as much water to do so. It is safe to say that most cultures that have thrived in arid regions have already unlocked this secret but for some reason it has not taken hold in America as one would expect. Fortunately without genetic meddling there is a number of plants that can produce ample crops with minimal water A few of these plants are listed below.
Fruiting Plants
Despite popular belief, it is quite possible to grow fruiting plants under arid conditions with good results. The key to fruit production under such conditions is to ensure soil quality and provide supplemental irrigation until the plants are well established. With some careful placement most fruiting plants can be quite productive.
- Figs, Olives, Persimmon, Pomegranate.
Vegetables
Vegetables are somewhat easier to utilize in a xeriscaping climate due to their adaptability and high nutrient value. Surprisingly certain vegetables even have ornamental value as their foliage can be quite attractive when used in the right combinations with other plants. Agricultural xeriscaping compatible vegetables can be broken up into several categories based on what parts you eat. Leaf vegetables include Amaranth, Asparagus, Chicory, Dandelions, and Prickly Pear. Vegetables where one eats the 'fruit' of the plant that work well with xeriscaping include Currant-type Tomatoes, Garden Huckleberry, Ground Cherry, Peppers, Prickly pear (fruit), tomatillo and wonder-berries. Grain vegetables should also be considered and they are a core staple, Sesame, Millet and Corn* are two good examples of drought tolerant grains. Lastly one must consider the vegetables in which we eat or use the roots. The root vegetable grouping includes Carrot, Chicory** and , Dandelion**.
Herbs
Thankfully growing herbs in arid situations is quite easy as many common herbs hate wet feet and will tolerate drought quite well once established. As a general rule of thumb, if the herb your considering has large soft leaves that bruise easily it is like unsuitable for use as a xeriscaping herb. Also one might also want to consider the herb's native range and if it can become invasive. For instance in the right region rosemary can become borderline invasive yet in others it is a well behaved shrub. Some reliable herbs for agricultural xeriscaping include; Artemesia, Eucalyptus, Germander, Lemon Verbena, Rosemary, Sage, Santolina, Tansy, Tarragon, Yarrow.
In short, with some good planning and careful site preparation one should be able to produce excellent quality food with minimal waste of water and use of resources. Despite what you might read in the horticulture magazines and see on television, xeriscaping does not have to be just for show. Check back on Friday for the next edition of LITFM's Xeriscaping series, the topic will be Ornamental Xeriscaping. Also I'd like tot hank everyone who has purchased a copy of the book, Southward Skies: A northern guide to southern gardening; thanks to all of you the first print run is almost sold out. A few remaining copies can be bought at Watching Booksellers in Montclair New Jersey! For those wondering The second print run is coming up will be available through amazon.com and will have some neat surprises included.
*only the heritage or heirloom types.
** The roots of these plants are used as coffee substitutes.

An Introduction to Xeriscaping
These days with climate change and other ecological issues we hear and see a steady stream of 'green' initiatives that can reportedly reduce your costs in time, efficiency and increase one or more positive aspects of certain things. Today I am discussing Xeriscaping, which by name is a portmanteau of the Greek word Xeros and the word Landscaping. Xeros for note means dry and the name Xeriscaping means landscaping without water. The truth to this is that unless your growing a hearty collection of rocks it isn't possible to really garden without water but it is possible to garden with heavily reduced water requirements.
For the purposes of this series, xeriscaping is broken up into three sub-sections; agricultural, ornamental, and natural. The three types will individually be discussed in the following articles in detail. Before we get to that series of concepts it is wise to make a key point about xeriscaping. Making a xeriscaped garden does not necessarily mean cactus, succulents or some sort of design resembling a pueblo seen in a wild west movie. A xeriscaped garden can be quite attractive if designed and planned right and even the placement of hard features such as boulders can aid the appearance.
The key to xeriscaping on the eastern coast is to think unconventionally, we know what xeriscaping is supposed to be but it will take some thought to determine what else it can be. as with any gardening concept the options are only limited by your climate and your own willingness to experiment with the plant material.
Next time we will cover the LITFM concept of Agricultural Xeriscaping, tune in Friday for more!

The Perils of G.M.O.
Originally August was to be dedicated to xeriscaping and in fact a few articles will be posted on this topic over the next few weeks to fill this void. But today I have an announcement, you can see me on TV! I was interviewed about my book "Southward Skies: A Northern Guide to Southern Gardening", on the Cumberland County Progressives TV show, the show is posted on the Cumberland County Progressives site at the link below.
http://www.cumberlandcountyprogressives.com/
The thing about Genetically Modified Organisms is that many do not understand the true scope of these creations and many are buried in the excessive hype surrounding them. For the record I do not support the propagation of GMO food in any shape or form. I would go so far as to say that the best legacy a Politician could have is the successful passing of a strict law or laws that force the clear and concise labeling of what is GMO and what is not on agricultural products and or chemicals.
One thing to clarify is the difference between a natural hybrid and a Genetically Modified Organism. A natural hybrid is normally the result of sexual reproduction between two naturally compatible plants within a similar genetic line. A good example of this can be found with the large varieties of tomatoes for instance the brandy wine types. In a good heirloom catalog one can find pink, chocolate, green, red and yellow brandy wine all of which result from natural pollination. A genetically modified organism is one that could not naturally exist because it requires delicate removal and introduction of genetic material to produce a species that otherwise would not have occurred in nature. A good example is 'Golden Rice', this variety of rice was altered to produce carotene in it's grains giving them a golden-yellow hue and additional nutritional value. Naturally rice comes in many colors but golden-yellow is not one of them so the breeders had to insert genes from a vegetable that produced carotene under normal circumstances. There is no way to tell how long or how many studies were made to ascertain the long-term health effects of this rice or if it was merely a white elephant of cereal grains.
Why are Genetically modified organisms bad? We do not know the long-term health effects of GMO foods for sure, Companies like Monsanto aren't exactly forthcoming with their study information and often will not allow independent third party investigations into their claims. Furthermore we have the problem of genetic aggression in GMO species. In central and South America, indigenous species of corn and maize are being bred out of existence by aggressive strains of genetically modified corn. For those who do not understand the biology of corn, it is wind pollinated, as such it's pollen can travel for many miles on a good breeze. This wind pollination means that if a neighbor a few miles up the road is producing starlink corn, and the breeze blows it's pollen onto your differing corn crop you now have genetically contaminated crops. This contamination leads to the destruction of numerous indigenous species of corn that have been cultivated for centuries.
Corporate irresponsibility and greed play a constant role in the proliferation of GMO species. A number of GMO food crops, particularly cereal grains are bred to be sterile. That is these crops produce seed but the seed will not germinate which forces the farmer to come back to the corporation yearly to pay high prices just to survive while likely going further and further in debt every year. Adding further insult to injury are the lawsuits over genetic contamination, which happens most in parts of the world where poverty is endemic and the local farmer can do little to defend him or herself against predatory multinational corporations. This sort of irresponsibility starts with a GMO crop that has not been fully tested, and then that crop produces pollen that is transferred in the usual ways to non GMO crops. When the farmer saves the seed of his crop for next year's planting he or she has no idea the seed is contaminated, and when and if it sprouts, the farmer gets a lawsuit for growing genetically copyrighted materials. When the farmer looses his land due to a legal battle for which he or she is often ill-equipped to fight, the corporation will often seize the farmer's land. In short both the crop and the crop's designer are opportunistic, and if it means more control more profit why change it?
As a last note the old saying 'You are what you eat' could not be more relivant today, because if you understand the digestive process, you realize that with every bit of vegetable or protein you eat, your stomach absorbs a bit of that food's DNA. How our body processes it on the molecular level is beyond my knowledge but I do understand that those materials don't just disappear. A few dietary studies have linked excessive protein uptake with cancerous growth, and cancer is what happens when genetics break down and do damaging things. So with that line of logic what then happens when you constantly ingest say GMO salmon that has been bred to be bigger, and by effect have more meat and be more aggressive?
Think about it, and tune in on Wednesday the 31st for the first of the xeriscaping series.

Welcome to August
As the summer heat continues to pummel the country LITFM presents a new summer article regarding a neat plant you may not have heard of; Solanum quitoense; commonly called Bed of Nails. Before I get into this weird and wonderful yet somewhat rare member of the nightshade family I would like to mention that the results of the Nightshade trials are fast approaching, results are due in August and believe me the results were not at all what was expected. Also I've been asked to be a guest on the Cumberland County Progressives TV show to talk about the book and some garden stuff. It airs on Time-Warner cable channel 7 and you can expect it will be posted after taping on the progressives site via Vimeo the Cumberland County Progressive's site is here:
http://www.cumberlandcountyprogressives.com/index.html
As soon as I know what days the show will air you can find it posted right here, and now here is a garden fact.
With the summer heat so high watering is harder then ever but did you know that if you follow four basic rules your effort is cut in half?
1. Determine if your wilted plant is wilting due to heat or dryness.
2. Always check pots, planters and raised beds thinner then 2 feet first.
3. Try not to waste water wetting leaves, this may damage some plants or promote fungal diseases.
4. Most plats under drought stress badly need about 1" of water a week, you can provide some of this by watering the base of the plant while counting aloud to 60. Note that fruiting plants may need signifigantly more and thus you can easily double the amount or reduce it as needed.
This is one of those plants that is so bizarre that it screams for more attention. Commonly mistaken with it's cousin the Devil's Thorn (aka Firethorn Nightshade) which is Solanum pyracanthium. Bed of Nails has more then ornamental value. The first thing to know about these strange members of the nightshade family is that they are covered in fine prickly hairs. These hairs can get lodged in the skin not unlike the fine needles on most cactus. Needless to say mature specimens have more developed needles and thus you want to wear gloves and plant these plants before the needles are developed. A mature Bed of Nails is a sight to behold. Large seemingly fuzzy leaves have brilliantly purple colored spines jutting out at somewhat regular intervals along the leaf margins and veins. The same spines appear along the stems which makes for a striking green, gray and purple color combination. Additionally some of the foliage may take on a purple hue which addes to the surprise value of the plant. I know what your thinking, 'Well thats nice and all but what do I get for all that prickly madness?'. Simply put Bed of Nails produces edible fruit. The fruit itself is a common staple in certain south American cuisine. The fruits, roughly the size of a golf ball, are often cut in quarters and eaten fresh with a little bit of salt. Otherwise the fruit can be squeezed for juice and be drank or used as a citrusy flavoring. Some recipes go so far as to use the Naranjilla juice as a replacement for lemon or lime juice.
There is one precaution about Naranjilla you should know, it looks exactly like a similar plant called Devil's Thorn that I mentioned earlier. Because of genetic variability with Naranjilla, it may be hard to tell the plants apart at times. I do not know if Devil's Thorn is edible so you should remember that the fruit of Naranjilla when cut in half while ripe will always have a green ring roughly where the seeds are.
As far as care goes Naranjilla is undemanding, it can tolerate drought if the soil is decent and can form impenetrable but annual thickets once established. For our climate it is an annual, but it will return from seed if positioned well. In climates further then hardiness zone 9 it should be treated as a annual. Otherwise you can harvest overripe fruit and collect the seed for next year. Occasional fertilizer treatments will aid it's growth greatly and if you want a heavy yeild feed it weekly. With summer temperatures reaching record levels this year I would advise you pay close attention to maintaining good watering practices.

The Heat Is On!
The heat of summer continues, but thankfully all you out there have everything you wanted planted already right? Well if not today I have three fun herbs to put on your must have list for the year. Todays plants of note are Pineapple Sage, Lemon Verbena and Lemon Balm but before I get into the trio of iced tea empowering herbs heres a gardening fact.
Did you know that 'Sage Brush' is actually three differing plants? There are three plants that depending on region are used as Salvia apiana, Salvia mellifera and Artemesia tridentata; or Sacred Sage, Black Sage and Mountain Sagebrush by common name respectively. Fortunately one of the three can be grown outdoors here in North Carolina, Black sage. For those in more northeastern climates if you can get one Mountain sage brush can be grown in containers to the point it makes an excellent bonsai plant.
Pineapple Sage is a commonly seen but rarely regarded herb found in most garden centers. In northern climates it is a absolute annual but in North Carolina, or zone 7 it is a tender perennial further south you can of coruse expect it will return yearly. Pineapple sage unlike most of the sage family does it's best when presented with protection from midday and afternoon sun. Ample moisture and a good soil will go a long way towards maintaining your stand of this sage. But what is it used for? Pineapple Sage has attractive red flowers that can attract hummingbirds and pollinators. The leaves impart a fruity flavor when cooked or soaked in a beverage. You can propagate pineapple sage stems by layering or through cuttings with rooting hormones.
Lemon Verbena is an unusual herb that has a dedicated following of gardeners who know in great detail it's virtues. Strangely enough Lemon Verbena is not seen in as many garden Centers as it should be. Why this herb has not caught on is beyond me. For those readers who don't know, This herb is the best lemon flavor and scented herb you can get your hands on short of an actual lemon. It is worthwhile to mention lemon verbena is actually in the verbena family and thus has exceptional drought, heat and poor soil tolerance. Furthermore Lemon Verbena makes for a attractive potted plant indoors for winter and cuttings root easily. In the culinary role if you have a recipe that calls for a lemony scent and flavor. The real joy of lemon verbena is in a tall glass of Iced tea at the end of a long work day.
Lemon balm is the most common lemon flavored herb of all time short of an actual lemon. It is rare to find a garden center without this herb on the racks in the spring. This is not due to marketing but that Lemon Balm is easy to grow and readily self-propagates from seed. The cultivation of this plant in the north versus the south does vary. In the northeast Lemonbalm can be grown in full sun with little issue and moderate supplemental watering and slight soil improvement needs. In the southeast Lemon balm is best grown in partial to full shade and needs regular water and soil with additional fertility and organic matter. As a herb Lemon balm is more scent then flavor. Few herbs can match the consistancy of the aroma as its sweet lemon fragrance when combined with real lemon can be a real seasoning powerhouse. Lemon balm does make a nice but somewhat thin flavoring for iced tea and in the right amount can make a refreshing tea all on it's own. Cuttings of lemon blam if you are so inclined can be rooted in water, but if happy it will propagate freely by seed.

It is worthwhile to mention lemon verbena is actually in the verbena family and thus has exceptional drought, heat and poor soil tolerance. Furthermore Lemon Verbena makes for a attractive potted plant indoors for winter and cuttings root easily. In the culinary role if you have a recipe that calls for a lemony scent and flavor. The real joy of lemon verbena is in a tall glass of Iced tea at the end of a long work day.
Melissa officinalis - Lemon Balm
Lemon balm is the most common lemon flavored herb of all time short of an actual lemon. It is rare to find a garden center without this herb on the racks in the spring. This is not due to marketing but that Lemon Balm is easy to grow and readily self-propagates from seed. The cultivation of this plant in the north versus the south does vary. In the northeast Lemonbalm can be grown in full sun with little issue and moderate supplemental watering and slight soil improvement needs. In the southeast Lemon balm is best grown in partial to full shade and needs regular water and soil with additional fertility and organic matter. As a herb Lemon balm is more scent then flavor. Few herbs can match the consistancy of the aroma as its sweet lemon fragrance when combined with real lemon can be a real seasoning powerhouse. Lemon balm does make a nice but somewhat thin flavoring for iced tea and in the right amount can make a refreshing tea all on it's own. Cuttings of lemon blam if you are so inclined can be rooted in water, but if happy it will propagate freely by seed.

The Okra Trials
Plant #6 proved to be the prize of the entire trial
The interesting part of this result is that it puts saved seed at odds with store-bought seed. Typically the seed from packs at the store is gray, where as the saved seed was almost black. it might be the variety or just the seed companies treatment of their seed materials.
Sowing Results:
12 seeds sown on 02-25-2011: 4 of 12 seeds germinated
24 seeds sown on 05-01-2011: 7 of 25 seeds germinated
Result: germination rate is 20% in general or about 78% if only dark colored seed is used.
The actual field trial saw the following placements of plants:
#1-3: Planted in Reinforced mound bed. (#2 petered out in early june for reasons unknown.)
#5-6: Used for 14" pot isolation trial. (#5 developed root rot in trials)
#7-8: Planted in Reinforced mound bed
#9-11: Loaned to two outside sites for true field trials.
This image is of plant #3, note the deep lobes in the mature leaves.
Needless to say the actual feild trials saw some interesting genetic variability, Plants 1-3 all displayed a deeply lobed thin-leaf 'filagree' leaf trait with additional red coloration. Plants 1-3 also displayed a noted lack of vigor. In contrast, plants #7-11 demonstrated moderate vigor, the maple leaf trait and even in feild trials have been found to be highly drought tolerant provided they have good soil. Plant #6 which is detailed below has shown to posses a trait for exceptionally large size.
As seen on a 90 degree day in full afternoon sun little wilt is presented despite the plant's size.
Malvaceae Abelmoschus esculentus 'Clark's Colossal'
Type: F1 Hybrid, specimen #6
Overall growth average: 0.80 inches per day
Germination Rate: 30% overall, 78% among darker colored seed.
Days until Germination: 4-10 days
Days until Mature: 30 days
Height at flower bud set: 11"
Ripe Pod Size: 3-5"
Both of the leaf-traits are clearly visible in this picture, the maple-leaf and 'blood spot' trait
Leaves
Alternate, simple possibly upwards of 13 inches across. Normally can be found to be three to five lobed, the lobes are roughly ovate with acute leaf tips, a doubly-dentate margin and prominant palmate veins. Where the leaf and petiol meet there is a dark red coloration that fades along the upper surface of the petiole. Petioles can often be up to 0.20" in diameter and as much as 7.5" long.
Stem
Older stems are often largely straight however closer to the apical tip the plant takes on an zig-zagging shape. Overall the stem is somewhat glabrous, green, but with age it may attain a gray color.
Size
The estimated potential size based on prime growing weather from now until the end of september using prior growing trends indicates the specimen could be upwards of 4-7 feet. The lower end of the range represents a plant grown in a 14" or larger pot with optimal soil and water. The Upper end of the size range is based on the sample being planted in-ground with optimal soil and water.
Hardiness
possibly 9.0 to 11.0 but typically grown as an annual.
Habit
Under optimal conditions this hybrid is upright with leaves born on exceptionally thick and long petioles. Side branching seems opportunistic only appearing on bare sections of the trunk perhaps due to latent cells. Generally the massive leaves can measure up to a 13" across and form a dence canopy that shades the central bud. The stems are thick, can withstand a lot of natural punishment and seem to rapidly reach 1" capipers with under two months. As a whole the plant has deffinate value in the garden
Rate of Growth
Slow to start but rapid once the temperatures stayed in the 80's.
Texture
The overall texture is the same in effect as the ornamental Castor bean, the foliage is exotic and each leaf is massive. This okra could be the non-toxic foliage replacement for the ornamental Castor Bean in the landscape.
Leaf Color
The leaves have a rich green coloration, this color is partly due to the heavy veins that add minute shadows and texture this darkening the surface of the leaves.
Flowers
Flower is typical of a Mallow each is born solitary bears five clasped petals and is somewhat veriable in color, possible hues include white, cream, or pale yellow. Flowers are open for about 12-24 hours then promptly the petals wilt and the seed pod begins to form.
This picture was taken just a few days ago for scale, the okra is growing in a 14" diameter pot. the window pane behind it is 2' 2" wide. The okra is 29 inches tall. At the time this picture was taken the largest leaf was 14" wide by 13" long. #6 is the largest specimen on the trial and the only one to show this 'giant' trait.
