Redbuds With Awesome Summer Foliage

Native redbuds Cercis canadensis) is native to eastern and central North America (USDA hardiness zones 4-8). This small tree is a highly dependable small flowering tree.

Smoketrees For Their Multi-Seasonal Appeal

Smoketree or smokebush (Cotinus coggygria) is a large shrub or small tree native from southern Europe to central China (USDA hardiness zones 5-8). Over time it typically matures to 10-15 feet high and wide. Depending on cultivar (see list below), smoketrees have oval leaves tinted in rich purple, gold, or green shades. Generally, they grow […]

Six Perennials For Dry Shade

Many of the following perennials tolerate dry shade but flourish in moist, well-drained soil. Each typically displays the richest foliage colors with a couple of hours of direct sunlight a day. All hold up well to dry conditions and are deer and rabbit resistant. Barrenworts (aka Bishop’s cap, Fairy Wings) (Epimedium spp.) represent over 70 […]

Rhododendrons You Should Be Growing

“A healthy plant in the right place with proper maintenance” is a rhododendron that has few problems. Rhododendrons and azaleas are acid loving plants meaning plants should be planted in humus-rich slightly acidic soil (pH 5.2 -6.5). If the soil is not well amended, rhododendrons will have trouble surviving long term. Once planted, water during […]

Dependable Conifer Trees For Southeast U.S. Landscapes

Arizona cypress (Cupressus arizonica var. glabra) is a southwestern U.S. conifer tree that is often underplanted. Soil drainage is an absolute must! Growth rate is moderate (15 feet high after 10 years) and eventually will reach 30-50 feet at maturity. (zones 7-9). I have seen multi-year specimens thriving in zone 6b. Deodar cedar (Cedrus deodara) is […]

Some Conifers Don’t Like Summer Heat And Clay Soils

Most conifers are best grown in deep, moist, well-drained, acidic loamy soils and in full sun. In the deep South evergreen conifers are challenged by warm soils, poor soil drainage, and humidity. Humidity increases their susceptibility to diseases. Once established they are drought tolerant, but most fail in poorly drained wet soils. Many pine species […]

Zone 6 Hardy Camellias

Once upon a time, across the Southern U.S., camellias were highly prized for their showy flowers in the fall-winter landscape. What has changed is that gardeners in the Middle Atlantic and mid-Southern states can now grow them equally well. Camellias are evergreen woody shrubs native to Asia. Currently, after decades of inter-breeding with species from […]

Care Of Rhododendrons

In the U.S., two species of rhododendrons, Catawa (Rhododendron catawbiensis) and Rosebay (R. maximum), are plentiful in the Appalachian Mountain region. Their roots feed in part on the rich humus material in the rocky mountain soils. Over time fallen leaves, twigs, and flower parts decay into additional humus. Humus improves soil aeration and drainage, yet […]
