Nellie R. Stevens Holly

  Hollies and the winter season work well together. Female hollies with bright red fruits (yellow-fruited forms also) contrast with their glossy evergreen foliage. ‘Nellie R. Stevens’ holly (NRS), a female form, is a cross between English (Ilex aquifolium) and Chinese (I. cornuta) hollies. NRS is the popular holly choice in Southern landscapes (USDA hardiness zones 6 to 9). Hollies are dioecious, […]

Provide Space For Weeping Blue Atlas Cedar

Atlas cedar (Cedrus atlantica) hails from the Atlas Mountains in northern Morocco and Algeria (USDA hardiness zone 6-9). ‘Glauca Pendula’ is a popular weeping form with blue green needle foliage. It is found in limited quantities at full service garden centers. Mature forms of weeping blue atlas cedars take up lots of space. When young its natural weeping form perform as a […]

Conifers For Poorly Drained Soils

Before planting conifers in your landscape, it’s absolutely important to know the drainage (percolation rate) of the soil, particularly if it is clay-based. Most conifers prefer well-drained sandy and clay loam soils. To determine your soil type and rate of drainage, try the “hole test” recommended by Virginia Tech University horticulturists. Dig a hole approximately one foot deep […]

Emerald™ Arborvitae

Emerald™ or ‘Emerald Green’ arborvitae (Thuja occidentalis ‘Smaragd’) is not new shrub or cultivar. More than 3 generations of gardeners have used this unique form of eastern arborvitae as their “go to” evergreen shrub up and down the eastern coast and through the Midwest (USDA hardiness zones 3-7). Emerald is a semi-dwarf evergreen shrub with a […]

Lacebark Pine Is An Arboreal Gem

Lacebark pine (Pinus bungeana) is an arboreal gem which few gardeners are privileged to own (USDA hardiness zones 4-8). Hopefully, this will change. Lacebark is a lovely 3-needle pine with exquisite exfoliating bark which becomes more attractive as it ages. Bark mottling begins after 8-10 years, that’s worth the wait if you’re a young patient […]

Tips On Crape Myrtles In Fall And Winter

                  Hardy cultivars of crape myrtles are best left alone in the fall. Light pruning to remove a broken branch or the seed capsules is ok, but major pruning should wait until early spring.  “Crape murder” is a common practice in the Southeast U.S. and is not recommended any time or place. It involves lopping […]

Dragon Eye – Actually Four Different Pines

              In U.S. nursery catalogs, at least four gold striped needle pines are designated “Dragon’s Eye Pine”. They are Japanese red pine (Pinus densiflora ‘Oculus Draconis’), Japanese black pine (P. thunbergi ‘Oculus Draconis’), Variegated Korean pine (P. koraiensis ‘Oculus Draconis’) and Variegated Himalayan pine (P. wallichiana ‘Zebrina’) (USDA hardiness […]

Trees And Shrubs That Grow In Poorly Drained Soils

If a section of your landscape is poorly drained, there are a number of trees and shrubs that will adapt over time to short periods of wet or soggy soils. Plant roots must survive in low oxygen soils. Your choices of plants are not lengthy; few landscape plants will not tolerate root suffocation for even […]

Better Choices Than Leyland Cypress For Privacy Screen

For homeowners in a rush to establish a tall green privacy screen from the neighbor(s), perhaps a 12-foot tall green fence may be your better option. Among the choices of evergreens to plant, Leyland cypress (x Cupressocyperus leylandii) is fastest growing, but is plagued by any of three serious disease problems. An established leyland cypress planted 12 feet apart completely […]
