Merlot Redbud is Drought- and Heat-Tolerant with Wine-Colored Leaves

Raise a toast to this drought- and heat- tolerant redbud with Merlot-colored leaves. Merlot Redbud (PPAF) is the preferred vintage for those gardeners in hotter, drier zones (U.S.D.A Zones 6 – 9) looking for a small ornamental tree with dark foliage. A cross between Cercis canadensis 'Forest Pansy' and Cercis canadensis var. texensis, Merlot Redbud is much more drought- and heat- tolerant than eastern redbud trees and has appealing shiny wine-red foliage that laugh at heat.

The glossy leaves of Merlot Redbud are dark wine-purple like the color of a fine Merlot wine and are smaller and more rounded, free of scorch well into fall. The reduced size and rounded shape (without a point) accommodates the stress of hot climates, while the shiny leaf surface slows transpiration or water loss of this hybrid redbud.  These strategies to ‘beat the heat’ are inherited from their texensis parentage, and thick, glossy Merlot Redbud leaves hold up well during the heat of Southern and Southwestern summers without browning margins.

At 12’ x 15’ Merlot is the perfect tree for small yards. Overall the small ornamental tree has as a semi-upright vase-shaped growth habit. The plant is tighter and denser than Cercis ‘Forest Pansy’.

Mature trees flower heavily with strong, bright magenta-pink flowers on bare branches. They are self-cleaning and have a low seed set. Thus the homeowner or landscaper enjoys a heavy bloom but the seed pods tend to drop early before ripening and turning brown, and don’t hang on the tree. These flowers are attractive to bees, butterflies and nectar-loving birds.

The name ‘Merlot’ means ‘young blackbird’ in French, after the dark maroon-black color of both the varietal grape from Burgundy and the leaf of this redbud, a ‘grand cru’ among Cercis cultivars.

Unique Ruby Falls Redbud Combines Deep Color & Weeping Habit

.

The exciting landscape potential of this new cultivar is electrifying the nursery industry. 

Ruby Falls Redbud is exploding off the charts of woody plant desirability as an entirely new variety, displaying purple foliage on a small weeping form of this native understory tree.  A new and distinct cultivar, this attention-getting combo of features sets Ruby Falls apart from all other existing cultivars of redbud tree.

Ruby Falls, an F2 hybrid, inherited its weeping form from one parent plant: the weeping green 'Covey' redbud (aka Lavender Twist™), and its dark ruby-purple leaf color from another parent: 'Forest Pansy' redbud.  In combination these traits set Ruby Falls apart as a new specimen form.  

Weeping, pendulous, cascading Ruby Falls Redbud exhibits an excellent branching structure.  Zig-zaging branches form a cascading crown. The weeping tree reaches a moderate height of 4-6 feet and a spread 6-8 feet. 

Redbuds are true harbingers of spring. Ruby Falls blooms profusely in early spring when clusters of tiny hot pink rose-purple, pea-like flowers accentuate the bare, pendulous branches and mature trunks for 2-3 weeks (March-April) before the foliage emerges.  Flowers are attractive to pollinators and seed pods resembling snow peas appear in summer.

The rich, purple, heart-shaped leaves open bright ruby-purple in spring, then gradually mature to deep purple, and ultimately change to green as the season progresses. Fall color on this deciduous ornamental is yellow until leaf drop in early winter.  

Ruby Falls Redbud provides a spectacular pendulous waterfall of alluring color for garden and landscape and is perfectly suited to be a specimen or garden feature plant due to its eye-catching weeping form and large red foliage. Small gardens enjoy the elegance and small stature of Ruby Falls. The cultivar benefits from an exposure of part sun to shade and is easily grown in a range of well-drained soil types; do not overwater.  It is hardy in U.S.D.A. Zones 6 – 9.  Birds, butterflies and bees find Ruby Falls attractive and visit frequently.

White Frost™ Birchleaf Spirea from Garden Debut

Growing up in Ohio, several rounded shrubs of the straight species of Birchleaf Spirea, Spirea betulifolia, grew across the back of our neighbors’ garage. Reliably every spring or early summer, fountains of white flowers (actually flat-topped cymes of tiny flowers) would coat each arching branch of this rounded native shrub. We called it “bridal wreath” and one tiny cyme was just the right size for a Barbie doll wedding bouquet.

The new White Frost™ Birchleaf Spirea from Garden Debut®  is an improvement over the species, with a lovely range of fall color including shades of purple, orange, yellow and rust. In summer, the leaves are a dark green and iridescent silver-green beneath. White Frost™ is a long-lived, deciduous shrub that grows at a moderate rate to reach a height and width of three feet. In the Rosaceae, its tiny white flowers are attractive to bees, butterflies, and birds, but this cultivar is sterile and does not set seed. 

White Frost™ Birchleaf Spirea has average water needs but a low tolerance to drought. It is adaptable, accepting a pH of 5.5 to 7.5 and /USDA Hardiness Zones 3 to 8. It is also good in containers. White Frost™ Spirea is botanically known as Spirea betulifola ‘Tor’ and is vegetatively propagated by permit. Contact your independent Garden Center to locate this shrub for your garden. 

Crown Jewel Gardenia does well in Acidic, Loamy Soil

Crown Jewel® Gardenia PP19896 is a low-growing, spreading to prostrate Gardenia with intensely fragrant, white, medium-sized flowers in early summer.  Bright green foliage is medium to small sized for the species.  While cold-climate gardeners must grow their gardenias in pots, in USDA Zone 7 and warmer gardenias are grown outdoors, permeating the garden with fragrance.

Providing an acidic loam is crucial for plant health and successful blooming in some plants. Gardenias, along with blueberries, fragrant native azaleas and beautiful evergreen camellias, all prefer moist, loamy, acid-rich soils with the pH ranging between 5 and 6. Amending the soil with organic soil conditioners facilitates the development of the right blend. Compost made from pine needles, oak leaves or Douglas fir sawdust, followed after planting with a mulch of pine straw, goes a long way toward this goal. Soybean meal, cottonseed meal or alfalfa as a green manure also create more acid conditions.

Another organic tip is to add powdered sulfur to the soil a few months before planting according to package directions to lower the pH, making the soil more acidic (also a good tip for Iris ensata, Japanese Iris).

Iron Chelate is an organic form of iron, and provides micronutrients  in a form available for absorption by plants. Spraying the foliage with iron chelate typically eliminates yellow, mottled choloritc  leaves  deficient in iron by supplying iron and facilitating the uptake of nitrogen. 

These wonderful woody plants are best provided with full to partial sun (a bit of afternoon shade is great) and good air circulation in a cooler, woodsy environment. Don’t plant near the reflective heat of concrete or asphalt. Protection from cold winter winds helps to prevent tip dieback at the colder regions of the plants’  range. Light applications of commercial azalea fertilizer or diluted acid-forming fertilizers are ok, but too much can burn tender roots.

In particular, Crown Jewel® Gardenia was selected from a controlled cross between the dwarf ‘Kleim’s Hardy’ and the cold-hardy, twice-blooming ‘Chuck Hayes’ by Philip Dark of Oakmont Nursery in Chathem County, North Carolina. Heavy June blooming repeats until frost. Highly perfumed Crown Jewel® Gardenia grows about 6 inches /year with the potential to reach 2 feet in height and a spread of 4 to 6 feet wide, ideal for garden beds. Dark is a member of the consortium of growers and breeders that make up Garden Debut®.

Christmas Jewel(R) Holly and the Great Backyard Bird Count

Today, Friday, February 18, 2011 begins the Great Backyard Bird Count which runs through Feb. 21. Although it is called “Backyard” participants are encouraged to count in parks, woods, farms, and campuses for minimum intervals of 15-minutes. Then post the count on the website, sponsored by Cornell and Audubon. This Video explains in detail just how to participate.    

Since it is easy to count birds while they are distracted by feeding, consider planting berried shrubs to attract birds to the garden. An adaptable broadleaf evergreen shrub perfect as a specimen plant or grown as a narrow, dense hedge, Christmas Jewel® Holly PP14477 is a beautiful Ilex pernyi hybrid hardy in USDA Zones 6-9. Fifteen year old plants are 9' tall by 6' wide with an upright, dense pyramidal shape achieved naturally without pruning. Polished dark green leaves of Christmas Jewel® are small, narrow and long with blunt spines that are not very sharp to the touch. Christmas Jewel® Holly is a lovely, low maintenance addition to the landscape.

Christmas Jewel® Holly plants are female, producing abundant, large, apple-red berries without the need of a pollinator. The berries turn red before Christmas and last until early summer or until they are eaten by wild birds. Typically, birds won’t eat Ilex berries until late in the winter season when they have been softened by alternate freezes and thaws.  

According to docstoc, holly berries have among the highest nutritive value for [British] berries with a value of 4.75, and these highly nutritious berries that are available at the right time of year.

Bird species that eat holly berries include flickers, mocking birds, thrashers, flickers, catbirds, waxwings, cardinals, blue jays, as well as mourning doves, ruffed grouse, bobwhite and wild turkeys. Deer, voles, squirrels, chipmunks, rabbits, hares and even bears, red foxes, raccoons and box turtles all eat holly fruit.

Some birds like robins normally eat insects and worms, but become fruit-eating birds or frugivores in late winter, and the nutritious red holly berries are available to them.

By planting Christmas Jewel® Holly or other berried shrubs in the landscape, your  bird species counts may be enhanced for the Great Backyard Bird Count.

Bare Root, Container-Grown and Balled-and-Burlapped Woody Ornamentals

Right now in late winter is the second best time to plant woody ornamentals (the best time is in the autumn). Choose from woody plants growing in containers, field grown with balled-&-burlapped root systems, and bare-root plants.

1. Container-grown plants are the most common source for nursery stock, are widely available and provide the best success for gardeners. The potting mix in the container is filled with vigorous white roots just hitting the sides of the pot. First, loosen a wide area of soil in the new garden site, dig a hole nearly the same size as the pot (but not deeper), and pop in the rootball, firming the surrounding soil and watering in thoroughly. Nothing could be simpler!  

Occasionally, the plant has been in the container too long, and the roots may have begun to circle around inside the pot. Either tease them out and point them in divergent directions in a wider planting hole, or else eliminate circling roots by trimming off with sharp pruners. Another possible red flag to consider with containers is die-back due to the sun striking one side of the pot and baking the roots on that side due to the heat. Choose shaded containers.

The majority of my garden plants are purchased as container-grown, with the added advantage that they can be planted 12 months out of the year. Another bonus is that multiple sizes (and prices) are often available, and I can often choose an economical smaller size.

2. Balled-&-Burlapped plants, often abbreviated as B&B, are mainly larger-sized, field grown trees and shrubs that have been dug out of an in-ground nursery with a ball of soil around the roots. Great care is taken to wrap the entire sphere (typically 1 to 3 feet in diameter) in burlap and then tie it securely at the base of the trunk, ready to be transported.  Depressions are made in the sales yard for these balled plants, and they are heavily mulched and carefully watered until sales day. The great advantage of B&B plants is their larger size, providing a more mature look when planted in the landscape. 

Avoid split or cracked root balls, or root balls that have become dried-out with wilted shoots and leaves. Pick B&B plants up from the bottom of the soil balls and don’t grab the trunks to sling around. When planting, remove every bit of burlap and fasteners to give the root ball contact with the native soil. Roll it to one side, then pull off the burlap and roll it into the hole, making sure the trunk is perpendicular to the ground 

before firming the surrounding soil and watering in.

I have had good success with a lush Doublefile Viburnum, a pink Eastern Dogwood and six large, 3-inch caliper Southern Magnolias planted as B&B specimens.

3. Bare-root plants are harvested only in the winter when dormant, and all soil is washed away from the roots, leaving them “naked” or exposed. Bare-root plants have the advantage of being light in weight therefore cheaper to ship over distances, providing a wider selection of unusual varieties available from individual specialty growers. When bare-root plants are received, visually inspect for extensive, healthy white or creamy root systems, and avoid dried out roots, slimy black waterlogged roots, and plants prematurely breaking dormancy.  When planting, build up a cone in the middle of the hole and set the bare crown at or slightly above the soil level but not below (peonies are a special case). Spread the roots out in a 360 degree pattern to take advantage of the entire soil volume available. Bare-root plants typically establish more quickly because the roots can be spread out and become acclimated to the native soil.

Roses, fruit trees and vines, and perennial veggies such as asparagus, horseradish and rhubarb are most commonly sold bare-root.

No matter how you get your plants, care for them by providing a light organic mulch and watering until the roots are well established. Have you had good success with one of these? Let us 
hear from you!
