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 […]

Million Bells (Calibrachoa)

              Among gardeners “million bells” or “callies” are common names for calibrachoas (Calibrachoa x), spring-summer-fall flowering annuals; they’re closely relative of petunias (Petunia spp.). Low spreading plants are blanketed with small petunia-like flowers from spring until frost. Blooms hold up well to rain showers and do not need to be deadheaded. Plants are heat-tolerant and disease […]

Why Mophead Hydrangeas Do Not Bloom

      The introduction of Endless Summer® hydrangeas in the 1990’s got gardeners excited about growing mophead hydrangeas  (Hydrangea macrophylla) again. Mophead hydrangeas bloom both on old wood in the spring and again on new wood in mid-summer. Flowers have either a blue/pink color depending on the pH of the soil. Endless Summer hydrangeas bloomed […]

Little Bluestem – Beautiful And Environmentally Correct

                Little Bluestem (Schizachyrium scoparium) grows in old fields, meadows and prairies, and along roadsides across the United States and Eastern Canada (USDA hardiness zones 3-8). It forms dense clumps 2- 3 feet tall and 12 -18 inches wide. This warm season grass prefers a well-drained soil and […]

Double Knockout® Roses

Knockout® roses continue to wow gardeners across the U.S. (USDA hardiness zones 5 to 9). The original Knock Out series grew 5 to 8 feet tall and 4 to 6 feet wide. Shorter growing Double Knockout® series make better fit in most urban gardens at 3 to 4 feet high and 3 to 4 feet wide. Double […]

Basic Hosta Facts

Hostas are the most popular shade perennial in the U.S. They prefer a moist, compost-rich, well-drained soil. In northerly areas (USDA hardiness zones 4-5), where summers are cooler, most hardy cultivars grow in full sun. In warmer zones those in full sun must be irrigated frequently. Blue leaf cultivars look their best only in shady areas; the white waxy coating, responsible […]

Rose Care Starts With A Good Planting Site

Roses should be planted 4 feet apart on a garden site that receives 6 to 8 hours of sun. The garden soil must be well-drained and  pH between  6.0 and 6.5.  Prevent disease problems by providing good air movement between plants and not crowd them. Spring thru mid- summer is an ideal period to plant roses to allow […]

YoYo Winter Temperatures– Expect Flower Losses On BigleafHydrangeas

              In the Southeastern U.S. region, wildly fluctuating temperatures this winter will likely destroy or delay spring and summer blooming on bigleaf (mophead) hydrangeas (Hydrangea macrophylla) (USDA hardiness zones 6 – 9). Other hydrangea species, such as smooth hydrangea (H. arborescens), panicle hydrangea (H. paniculata), and oakleaf hydrangeas, should not be affected. Bigleaf hydrangeas are […]

Growing Zone 6 Hardy Camellias 101

              Drs. William L. Ackerman with the USDA (deceased) developed bred a series of interspecific crosses between C. oleifera and C. sasanqua, C. hiemalis, or C. vernalis selections. Many, not all, are identified as the Winter series because they bloom in the fall into very early winter. Dr. Clifford […]
