Oleander (Nerium oleander) is an attractive evergreen shrub for warm climates. Indigenous to the Mediterranean region, it is popular in warm regions of the U.S., namely in western, coastal, and southern states (USDA hardiness zones 8-11). Oleander prefers moist, well-drained soil and a sunny landscape site. Established shrubs withstand dry and windy conditions along coastal areas. Brightly colored […]

My Search Continues For A Hardy Gardenia
The longer you garden, many plant species keep improving, including their winter hardiness. A few years ago, growing gardenias (Gardenia jasminoides) in a U.S. zone 6 garden was a dream. Today, hardy gardenias are a safe bet in zone 7 or in zone 6 in a protected area of […]
Red Abyssinian Banana For Tropical Looking Landscapes
Red Abyssinian banana (Ensete maurelii ‘Red Abyssinian’) is a tropical banana from high in the mountains of Ethiopia in eastern Africa. Its enormous reddish to purplish foliage and red – burgundy trunk adds a tropical presence to any garden. Compared to hardier banana genus Musa, Ensete does not produce root suckers […]
Pampas Grass – Have We Learned A Lesson?
Many areas in the mid-South and northeast U.S. (USDA hardiness zones 6 and 7a) learned a hard lesson in the harsh cold winter of 2013-14. Over the past decade gardeners had been lulled into zone bending, insisting on planting species from a warmer zone. One of them was pampas grass (Cortaderia selloana). Very few clumps survived here […]
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 […]
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 […]
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 […]
Winter Blooming Flowering Apricot
Flowering apricot (Prunus mume) is native to southeastern Asia(USDA hardiness zones 6-8). It is primarily grown for its mid to late winter bloom of pink flowers. This small 15-20 feet tall tree grows in average well-drained, acidic soils in full sun to partial shade. Avoid planting in heavy or wet soils. Most abundant flowering occurs in full sun. In the […]
What Roses Need
A goal of most rose gardeners (rosarians) is to grow them almost maintenance free. The improved shrub roses introduced almost two decades ago have brought this too reality. Rose series such as Knockout®, Home Run®, Drift®, OSO Easy®, Carefree® and Meidiland™ are among the best. No matter the pedigree of the rose, selecting a […]
Many Shapes and Sizes Of Cryptomerias
Japanese cedar, aka cryptomeria, (Cryptomeria japonica) is the national tree of Japan and is also indigenous to China (USDA hardiness zones 5 to 8). Cryptomeria cultivars vary greatly from very dwarf to rounded shrubs to large tree forms. Needle-like foliage may be dark green, medium green, golden or contorted leaves. Cryptomerias tolerate hot humid summers and […]
