Fire Master™ Black Gum PPAF thrives anywhere it’s planted



The perfect choice for a slow-growing native shade tree that is master of the autumn countryside, an ideal solution to landscape challenge areas and recommended as a long-lived commemorative tree.

Fire Master(TM) Black Gum is an easy care native shade tree introduced by Garden Debut(R) in late 2010 with exceptional coloration. In the wild, Black Gum (also known as Tupelo) grows across the entire eastern half of North America, but at low densities of 1 to 3 percent in native forests. Nyssa is one of the few species that is both fire resistant and shade tolerant, and both young and old trees show excellent growth even under dense shade, indicated by the species name, sylvatica, meaning woods. 



Landscape architects note that Black Gum grows in conditions that range from flooding to drought, and can grow on almost any type of soil or site, from swamps, floodplains and bottomlands to xeric sites, uplands and dry ridges. Nyssa is slow-growing which may explain its great longevity, being the longest-lived hardwood in the Eastern U.S. with a mininum age topping 650 years. 


With a pedigree like that, Fire Master(TM) Black Gum PPAF is the first choice for a slow-growing shade tree for any type of difficult landscape situation. And what's more, it adds show-stopping color to the canopy with new spring growth ranging from soft, dusty pink to red and lime, then maturing to shiny, dark green summer leaves. In fall, the foliage turns many shades of yellow, orange and reaches a firey climax of brilliant, Chinese-lacquer red on high-gloss leaves. Even the petioles and veins are red. 


This slow-growing, pyramidal tree matures at a height around 50 - 60 feet tall and spreading to about 25 feet wide after 40 - 50 years, a great size for many urban yards, ideal in scale, without towering over one- and two- story homes. 


For added horticultural interest, Fire Master(TM) Black Gum sports small, greenish white blossoms in spring, the source of nectar and pollen for Tupelo honey, followed by 1/2 inch ong purple-black fruits that resemble tiny prune plums with a waxy bloom. These are quickly eaten by birds and wildlife when they ripen in September (before other wild native fruits are ready), yet do not stain driveways nor decks. Its bark matures to medium gray and resembles textured alligator hide. Fire Master(TM) Black Gum is relatively immune to insects and diseases. 


Landscape uses for Fire Master(TM) Black Gum include: specimen use adding color, form and texture; as a shade tree; commemorative tree; planted at the sunny edge of woodlands; planted in the dense shade of trees or buildings; or selected for landscape problem areas such as wet, sticky soils or dry, parched ridges. Reduced maintenance required by this native cultivar syncs with faster contemporary lifestyles and the demand for lowered maintenance. Fire Master(TM) Black Gum was selected for resistance to insects and diseases, as well as for improved hardiness and general ease of transplanting and growth. 


The best color is produced in full sun, but Fire Master(TM) Black Gum also tolerates dense shade and will grow on a broad variety of soil types, so it solves many "problem areas" in landscape design. And because Fire Master(TM) Black Gum is so long-lived, it is the ideal dedication or legacy tree planted to commemorate happy occasions. Its versatility makes it an ideal commemorative tree to plant to recognize milestones in life.  


Keep newly planted trees moist for the season after planting while the roots grow into the native soil, and add an organic mulch to maintain soil moisture levels. After becoming established, Fire Master(TM) Black Gum has carefree watering needs.

Insights About Tough and Beautiful New Garnet Fire Loropetalum


New to the trade, retailers and landscapers are fired with enthusiasm about this tough and beautiful red-leaved shrub. 


Named for the brilliant deep red gemstone, Garnet Fire(TM) Loropetalum is an ideally-sized evergreen shrub due to its outstanding, shiny, dark burgundy foliage. Colorful deep maroon-red leaves persist throughout the year in zones 7-11, and add a blaze of color to the winter landscape. 

Known as Chinese Fringe Flower, hundreds of garnet-red, tassel-like flowers with narrow, fringe-like petals envelop the plant in late winter through spring. Individual flowers persist for weeks thus keeping the plant in bloom for months and beginning with sporadic flowering the previous fall. Honey bees appreciate the early pollen source and the flowers attract butterflies. Other common names for the genus Loropetalum include Chinese Loropetalum, Fringebush and Chinese Witch Hazel. Garnet Fire™ is a seedling selection of Loropetalum chinense 'Zuzhou Fuschia' originated by Ted Stephens who is a member of the Garden Debut(R) consortium of breeders, growers, retailers and marketers.  

The multi-faceted, luminous shrub reaches a useful 4-5 feet in height and tolerates direct sun to part shade for versatile landscape placement. Use Garnet Fire (TM) as a specimen or accent plant, in the border, in front of the foundation plantings, as a container plant, for massing or as a screen. It is striking when planted next to pastel flowers, or beside yellow- or silvery- blue foliage that emphasize the burgundy foliage. Garnet Fire (TM) Loropetalum is a a tough plant that tolerates heat, humidity, deer, rabbits and slopes. 

Traditionally, garnets were popular as a talisman and protective stone believed to light up the night and protect their bearers from harm. Like its namesake, Garnet Fire(TM) Loropetalum lights up the garden and protects the landscape from the monotony of too many green shrubs. Anyone who loves what is pure, natural and having the deep color of garnets will be fired with enthusiasm for Garnet Fire(TM) Loropetalum.

Shadyside on January 24, 2012


We're having one of those soft, gold-kissed mornings after days of rain; the fog burned off early and everything is damp and I can almost hear it growing. Golden sunbeams slant into my woodland and turn the salad burnet (Poterium sanguisorba) to glistening diamonds with a dewdrop on every point on every serrated leaflet of every compound leaf.

Phalanxes of individual green grass seedlings are sprouting up. It is a simple cover crop of annual rye grass (Lolium multiflorum) for now,   two inches high so far and brilliant green where I plan to have a small zoysia lawn in the future. This morning I tossed out more grass seed in the bare spots that I missed the first time. I mixed my seed with a mycorrhizal soil inoculant with an organic kelp and molasses base, plus I scattered two bags of lime to sweeten up the soil for good measure.

Last weekend we finished rooting out by hand the tall goldenrod (Solidago altissima), briers (Rubus spp.) and cat briar (Smilax laurifolia) from a sunny triangle about 20 feet on a side. Then we mulched it heavily with 18 wheelbarrow loads of rotted wood chips and I have high hopes for a new vegetable garden this summer. I limed the future garden too, and now pulverized dolomitic lime is on my shopping list once more.

Tearing myself away and dragging myself indoors to work on my presentation for GGIA 2012 Wintergreen this Friday.

The Winter Solstice is a Balmy Planting Day in Atlanta


Although it is late December and the shortest day of the year, we are having an incredibly balmy day in #Atlanta. I was delighted to spend 3 hours outside this morning under a light mist (or perhaps it was inside a low-flying cloud), planting Japanese irises along the sometimes-wet dry creek bed, star magnolia in a prime spot, forsythia near the road, plus camellia, hardy ageratum, Chinese sacred lily, Italian arum and 2 huge native azaleas. O, the anticipation of spring.

Everything is green and still growing; in fact the hardy ginger already is sending up spring sprouts. Ferns are thriving, Amarcrinum and Crinum still green, lots of fall-blooming crocus still photosynthesizing. Herbs that I planted almost a week ago look great as they begin to make contact with the rich brown soil. 108 Helleborus x orientalis that I grew from seed  and put out as quarts this fall are each beginning to offer a new leaf. Left over from summer, I still have late roses, Encore azaleas, pink daisy mums and yellow ones in bloom, as well as camellias blooming for the first time.

After awhile even my and hair face felt a little green and mossy. So satisfying to breathe the good, rich earth smells and suck in the endorphins. What a lucky gardener I am, to live in Zone 7B.

Summer Solstice 3 Ways: Science, Plant Photoperiodism & Lore


SCIENCE
June 21 is a significant day for Planet Earth and its relationship with the sun. The Earth spins on its axis, an imaginary line going through the globe between the north and south poles, with each complete revolution taking 24 hours. However, the Earth’s axis is tilted 23.5 degrees off the plane of its revolution around the sun, and so for several months of the year, one half of the earth receives more direct rays of the sun than the other half. The four seasons are a result of this tilt.

The Summer Solstice is the date when the rays of the sun directly strike one of the two tropical latitude lines. Astronomers in the northern hemisphere calculate that the summer solstice occurs when the sun reaches the Tropic of Cancer thus causing the northern hemisphere to experience the longest day and the shortest night of the year, June 21, 2011 at 1:16 p.m. EDT (17:16 UTC). Similarly, astrologers know this as the date on which the sun enters the sign of Cancer in the starry heavens.  Simultaneously it heralds the longest night of winter in the southern hemisphere. And far north of the Equator in the Artic Circle, there are 24 hours of daylight on June 21.

PLANT PHOTOPERIODISM

Plants respond to day length in direct ways. Photoperiodism is the term used to discuss plant responses to day length or more accurately, night length.  “Long day plants” (like clover, foxgloves and garden pinks) bloom as the days get longer and when the nights are short. 

After Midsummer, these plants stop blooming and other plants (like goldenrod and chrysanthemum) begin to bloom. These are called “short day plants” because they are triggered to flower as the days grow shorter (after the Summer Solstice) during late summer and fall. Well-known as a Christmas flower, the poinsettia develops its showy bracts as the year approaches the Winter Solstice, while the day length is decreasing and there are a long, unbroken periods of darkness each night.

Still other plants are “day neutral plants” because they are less responsive to the length of the dark period. Spring and Fall Equinoxes are the midway point of the solar year. (See also http://plantpreview.blogspot.com/2010/12/winter-solstice-full-moon-lunar-eclipse.html )

HISTORY & LORE

Awed by the power of the sun, for centuries civilizations have celebrated the Summer Solstice, also known as Midsummer, St. John’s feast day, or Litha. Although modern usage suggests that ‘summer begins’ at the summer solstice, the old folk calendar placed the beginning of summer on May Day (May 1) and the end of summer on Lammas (August 1). This more reasonably placed the summer solstice midway between the two, marking midsummer as the peak of old sun god’s strength.

The traditional Celtic Midsummer was celebrated on the fixed date of June 24, which coincides with the Christian feast of John the Baptist and his flower, St. John’s wort.  Faery lore held that Midsummer night was a time of magic, when pixies and evil spirits went abroad. To thwart them, people wore protective garlands of herbs and flowers. One of the most powerful of them was a plant called 'chase-devil', also known as St. John’s Wort, and is still used by modern herbalists as a mood stabilizer.

Other flower-based customs included decking the house (especially over the front door) with birch, fennel, St. John’s wort, orpin, and white lilies. Five plants were thought to have special magical properties on this night: rue, roses, St. John’s wort, vervain, and trefoil. St. John’s wort was picked by young maidens in the hopes of finding her true love.

St. John’s connection to the wilderness (from whence “the voice cried out”) was often emphasized by the rustic nature of his shrines, and by his alternate name, “the Oak King”. Perhaps the archetypal ‘Green Man’, or ‘wild man of the wood’, whose face appears through the leafy masks that adorn early Church architecture, was based on St. John.

Celts and Slavs celebrated the eve of the first day of summer with dancing and bonfires representing the sun's energy (Shakespeare’s Midsummer Night’s Dream, June 23), staying up all night to welcome the dawn
Couples would leap through the flames, believing their crops would grow as high as they were able to jump. Chinese marked the day by honoring Li, the Chinese Goddess of Light, in Spain it’s called the “Night of the Verbena (Vervain)”, while the Druids celebrated the day as the "wedding of Heaven and Earth", resulting in the present day belief of lucky June weddings. The Midsummer full moon was known as the "Honey Moon" for the mead made from fermented honey that was part of wedding ceremonies performed at the Summer Solstice.
