New Endless-Blooming Aruba Red™ Daylily Finds Favor

Continuous blooms from spring through fall add value to the landscape.

Superior to previous long-blooming daylilies because of its rich, saturated red color, Garden Debut®’s new introduction Aruba Red™ Daylily represents an advance in performance in color, long blooming season and disease resistance.  Plants in the Enjoy 24/7 “the no work plant collection” share outstanding characteristics that appeal to gardeners, homeowners, landscape designers and contractors. http://gardendebut.com/_catalog_67846/Enjoy247Daylilies

Aruba Red™ Daylily flowers are deep crimson red, with a heavy substance. Delightfully wide, overlapping, red petals recurve, creating a round flower form. Petals are heavily ruffled, with tons of ruffles continuing down the petal edges into an appealing yellow throat. Branched flower scapes have dozens of flower buds, enhancing the display.

Aruba Red™ Daylily is a 2011 introduction in the Tetraploid series Enjoy 24/7 “the no work plant collection” from Garden Debut® that features shorter plants with large, brightly-colored flowers. Flowering begins six to eight weeks earlier than standard daylilies and flowers develop even during cooler weather and cold nights, a big plus for retailers whose customers will be captivated by the colorful display on their springtime shopping trips.  Blooming continues throughout the summer and fall until cut down by hard frost (as late as Thanksgiving in Zone 7).

What’s more, Aruba Red™ is resistant to Rust that plagues previous long-blooming daylilies. Short, grassy foliage, clean shedding of old blooms, prolonged reblooming that extends the season, and rapid increase of divisions add up to a finer daylily. Compact plants with short flower scapes and foliage of this daylily eliminate blow-over in garden centers common to taller daylilies sold in gallon pots.    

The culmination of seven years of targeted plant modification by renowned author and daylily breeder Dr. Ted Petit of Le Petit Jardin, McIntosh, Fla. Garden Debut® is pleased to provide the green industry with superior plants through this new partnership. Kokomo Sunset™ Daylily was available in fall 2010. Future introductions in this daylily collection will continue with enjoyable names derived from the Beach Boys hit, Kokomo, and the flowers will evoke a tropical feel of freedom and fun.

Scentimental Journey with Sweet Treat™ Lilac


Beloved Lilac fragrance is combined with superior disease resistance and red to burgundy fall color.


The intoxicatingly sweet lilac fragrance so beloved of generations is enveloping gardeners through an improved selection known as Sweet Treat™ Lilac from Garden Debut®. Heavy with a profusion of blooms and redolent with a fragrance more perfumed than roses, this selection has also proven marvelously disease resistant, performing flawlessly in the brutal heat and humidity of lower Midwestern summers.

Sweet Treat™ Lilac presents a profusion of fragrant blossoms each spring that are dark lavender in bud and fade to a soft lavender-ice blue when fully opened. The plant is particularly floriferous when planted in full sun, and its fragrant blossom trusses stand out beautifully against dark green, glossy leaves. But there’s more. Sweet Treat™ has the best fall leaf color of any Lilac, when its green foliage turns a deep burgundy red, adding color in the autumn landscape.

Sweet Treat™ Lilac is well-branched, compact and upright-rounded in form, slowly growing to a height of five to six feet tall and a mature spread of four to six feet, with foliage stretching to the ground. It is small enough to be ideal for nearly every garden. Sweet Treat™ Lilac makes a wonderful addition to shrub borders or foundation plantings where proximity to a gate, walkway, patio or entrance door provides perfumed enjoyment. It grows well in a wide range of soil conditions and is hardy in Zones 3-8, making it the most versatile lilac in the country. 


Sweet Treat™ is a great improvement over the well-known variety of Dwarf Korean Lilac, Syringa pubescens subsp. patula 'Miss Kim'. Sweet Treat™ Lilac reliably displays clean foliage and vigor with no disease or die back during the hottest summer temperatures, that normally sound the death knell for the older variety.

Native Shade Tree Snow Flurries™ Black Gum Has Variegated Leaves


Attractive white-margined leaves on this native shade tree are unusual.

Anticipating the first flurries this summer! An easy-grow native shade tree, Snow Flurries™ Black Gum has unbeatable green and white summer color, rare in the world of shade trees. Snow Flurries™ has shiny, variegated leaves with generous white margins and green centers and is riveting in the landscape. Garden Debut® expects a blizzard of orders once this extraordinary plant hits the market. Overall, the variegated leaves are narrower and smaller than the species, turning a ruddy color in early autumn.

The tree reaches 30 – 40 feet in height, with gracefully draped lower limbs creating an oval form. This Garden Debut® introduction is easy-care and trouble-free. Snow Flurries™ has clean leaves without leaf spot and with no significant pest problems. Aided by its deep tap root, it is adaptable to an extremely wide variety of soil moisture conditions from poorly drained soils and low spots subject to periodic flooding, through average garden soils, and also on dry sites.

Small flowers are a great nectar source and attract honey bees resulting in prized Black Gum or “Tupelo” honey. Small, dark blue, football-shaped fruits are a favorite of birds and wildlife in August and September, and do not stain decks or paving.  Left, leafing out in early spring.

Fire Dragon® Shantung Maple Flames Red


Maple Selection Brings “New England Red” Color to Midwestern Fall Landscapes

Fire Dragon® Shantung Maple delivers vivid reds and dazzling scarlets rarely seen in the Midwest or lower-Midwest landscape in autumn. A tough, hardy and well-behaved mid-size maple (to 35 feet), Fire Dragon® is the first introduced selection of Acer truncatum, commonly known as Purple-blow or Shantung Maple (pronounced ‘Shan-doon’ ).

Fire Dragon® was selected from thousands of seedlings for its glorious, brilliant red fall color so elusive to the lower-Midwest. Finding a consistent red for hot, sunny climates has long been a challenge for plains states gardeners and designers. With the straight species, new spring foliage is a beautiful reddish-purple leaf color in spring (“purple-blow”), turning to dark green for summer, then presenting brilliant yellow color in fall. However, each autumn Fire Dragon® reliably provides the sought-after, luminous reds found in New England to the Midwest (and the rest of the country). Grower Keith Johansson has observed three different autumn reds (anthocyanin compounds based on soil pH and environmental factors) including: bright, true, cardinal red; currant red with Chinese yellow margins; and a compelling reddish-orange. 

Spring and early summer leaf color on Fire Dragon® turns from burnt orange to pink and rose-red, and then to bright red when growing vigorously in May. Red pigments help protect the new leaves from ultra-violet rays and from insects until they can harden-off.  Summer leaf color is a pleasing, sparkling green on thick, waxy leaves; lowered transpiration rates help trees thrive in hot summers. New summer growth put on by this cultivar is typically a dark red throughout the season, although it may vary with temperature, soil pH, soil nutrients or levels of sunshine, and can range from dark red to brighter red to mostly green.

The elegant, distinctive leaf shape of Fire Dragon® is reminiscent of curly parsley. The species name, truncate, refers to a broad, flat leaf base at the petiole, however, the two basal lobes of Fire Dragon® face downward. While most Shantungs have a larger central lobe, in Fire Dragon® the leaf lobes are equal in size and fit inside a perfect circle.

Small, lemony, greenish-yellow flowers appear in late spring on 3-inch corymbs, followed by winged, purplish samara fruits that form a 90 degree angle.

Young bark on Fire Dragon® can have a purplish tone and eventually turns grayish brown, while older bark is two-toned brown, heavily fissured, and very attractive. Shantung maple branches are flexible but old wood is dense and very hard, much like an oak, and according to a Kansas State University study they were the least damaged/best performing in ice storms, and are similarly good for windy sites. 

Fire Dragon® Shantung Maple has a very efficient, non-aggressive root system that is reminiscent of a Japanese maple. Shantung is a preferred maple for under-planting in park and landscape settings because it is not shallow-rooted like some notorious maples, so the roots do not over-compete. In addition, the canopy provides open shade, perfect for an understory of rhododendrons, native azaleas and other ornamental shrubs, perennials and groundcovers. 

Acer truncatum is a very lovely medium-sized maple tree reaching up to 35 feet in height and spread. Growth habit is low-branching, round-headed, quite dense and uniform. It is a hardy, adaptable species, tolerant of heat and drought, with no serious pests. This tree is tougher than and just as beautiful as any maple growing “back east”. Hardy and heat tolerant, it grows on both acidic and alkaline soils. Shantung maples are in high demand in the lower Midwest and are gaining popularity throughout the upper-Midwest and upper-South to the east coast.

Fire Dragon® tolerates pollution and fits most urban landscapes. About the only thing it will not tolerate is poor drainage. With a vigorous growth rate, Fire Dragon® Shantung Maples grow 2 to 5 feet per year. This very lovely maple has application as a street or residential shade tree.

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.
