Flame Azalea Favorite Among Native Azaleas

Flame azalea (R. calendulaceum) is a spectacular sight when it flowers in early May through June (depending on location). The mountainsides across the Appalachian region seem to be afire with their yellow, orange or red flowers (USDA hardiness zones 5 thru 8). Its native habitat is in open, dry sites in woods, on the hillsides, and […]

‘Short and Sassy’ Helenium (Sneezeweed)

Sneezeweed (Helenium autumnale) is a bee/butterfly friendly perennial that blooms heavily from mid-summer into early fall. Helenium (“sneezeweed”) does not cause hayfever or irritate sinus passages. The genus Helenium is named for Helen of Troy. Its dried leaves were once crunched to make a snuff to promote sneezing. This tough prairie native thrives in full […]

American Yellowwood Deserves To Be Planted More

    American yellowwood (Cladrastis kentukea) is a beautiful native tree which  is rarely planted in U.S. landscapes (USDA hardiness zones 4-8). Yellowwood is a tree for all seasons. It is both a lovely shade and flowering specimen. Long white wisteria-like flowers appear in mid- to late-May. It eventually matures into a lovely 35 to […]

Cosmos For Sunny Gardens

Cosmos, indigenous to Mexico and South America, are one of the easiest-to-grow flowering annuals. They start blooming in early summer and are at their best in late summer and early autumn. Two most popular species are Cosmos sulphureus and C. bipinnatus. Flower heads are composed of disc and ray flowers. Cosmos is a member of the aster […]

Chinese Fringetree Gains In Popularity And Availability

 Chinese fringetree (Chionanthus retusus) When in bloom in mid-spring (May), the fringetrees (Chionanthus spp.) definitely will catch your eye. Chinese fringetree (C. retusus), is one of the finest small to medium sized flowering trees, not to be confused with the U.S. native fringetree (C. virginicus) (USDA hardiness zones 5-9). Both produce spectacular white lacy flowers […]

Good News About Garden Impatiens

  Gardeners no longer have to give up growing garden impatiens (Impatiens walleriana). No, the worldwide disease outbreak of downy mildew  on garden impatiens is not over. But new disease resistant cultivars of impatiens are arriving at garden centers this spring. Two of the newest are: SunPatiens® Spreading Shell Pink and Bounce® Pink Flame (‘Balboufink’). […]

American Fringetree – A Spring Flowering Treasure

American fringetree (Chionanthus virginicus) is one of the finest spring flowering trees (USDA hardiness zones 4-9). Individual flower heads are large and billowy, snowy white, and very fragrant in the early evening hours. Flower panicles peak through the large leaves, and are large and showy compared to Chinese fringetree (which I also like). Leaf sizes […]

New ‘Pam’s Mountain Bouquet’ Kousa Dogwood

  ‘Pam’s Mountain Bouquet’ is a new Chinese dogwood (Cornus kousa) cultivar from the plant scientists from the University of Tennessee Dogwood Working Team (USDA hardiness zones 5-8). Mountain Bouquet is a near-white flowering form whose petal-like bracts fuse into near perfect squares. The cultivar blooms slightly later than other flowering dogwoods, helping to extend dogwood’s […]

Gomphrena (Globe Amaranth) For Summer Easy Color

                  Gomphrena, aka Globe amaranth, is an annual bedding plant that blooms profusely in the summer heat and sun. Small ball-shaped flowers are clove-like  in appearance. Many gardeners tend to ignore them at the garden center for showier flowering annuals. By mid-summer, a peek into your neighbor’s yard may cause to rethink that decision. Gomphrenas […]

Less Invasive Rose Of Sharons (Altheas)

            In several states rose of Sharon or altheas (Hibiscus syriacus) are classified as exotic (non-native) invasive shrubs (USDA hardiness zones 5-8). Their seedlings are invading U.S. woodlands. Plant breeders are now developing less invasive cultivars. The double-flowered altheas produce far fewer fertile seeds; stamens and pollen sacs are mostly embedded within the flower petals. Azurri Blue Satin® is […]
