Three Standout Pfitzer Junipers

Pfitzer junipers (Juniperus x pfitzeriana) are standouts in the winter landscape (USDA hardiness zones 3-9). Many varieties are utilized as groundcovers. Pfitzers are easy care, low maintenance plants when properly sited in full sun and well drained. Around coastal areas, pfitzers are moderately resistant to salt injury. Give pfitzers lots of space. Their plume-like evergreen […]

Four Tree Conifers Which Should Be Planted More

Nordmann fir (Abies nordmanniana), aka Caucasian fir, is native to the Caucasus Mountains (USDA hardiness zones 4-6). This dense pyramidal conifer grows to 50 feet tall and 20 feet wide and are typically branched to the ground. Their flat dark green shiny needles (up to 1 ¼ inches long) feature two white bands on the […]

Fire Chief™ Arborvitae

Fire Chief™ Arborvitae (Thuja occidentalis ‘Congabe’) is a compact, globe-shaped evergreen that grows 3-5 foot high and wide (in 10 years) (USDA hardiness zones 5-8). It is at its best in full to partial sunlight. Its soft scale-like foliage changes color seasonally. New spring growth emerges orangey-red, turns bright green in summer, and develops a […]

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 […]

Five Evergreens For Small Garden Spaces

The following five evergreen shrubs are smaller versions of the larger growing species. They make a better fit in smaller urban gardens. Gyokuryu Japanese cedar (Cryptomeria japonica ‘Gyokuryu’) is a fast-growing, broadly conical selection with coarse bluish-green evergreen foliage. The needles are highly ornamental and remain bluish-green through most of the winter in zone 6 and […]

Comparing Western Red Cedar And ‘Green Giant’ Arborvitaes

Western red cedar or giant red cedar (Thuja plicata) is native to the Pacific Northwest. In the eastern U.S. it is called western arborvitae and landscapers typically do not plant it. Instead, they plant the hybrid cultivar  ‘Green Giant’ arborvitae, a cross between western red cedar (T. plicata and Japanese arborvitae (T.  standishii). Western arborvitae […]

Japanese Larch Is Preferred In Northern U.S.

Larches (Larix spp.) are majestic deciduous conifers in their northern ranges of their habitat (USDA hardiness zone 4 to 7). However, trees do not prosper in hot and humid summers south of USDA Zone 7. One of the best is Japanese larch (Larix kaempferi), but unfortunately, it is not commonly planted in U.S. landscapes. The tree averages 50-60 feet in height and 25-35 […]

Eastern White Pine Losses Continue

Environmental and pathogenic problems continue to take their toll on Eastern White Pine (Pinus strobus). This valued landscape and lumber tree is native in the Eastern U.S. and Canada (USDA zones 3-8). Climate change is likely contributing to recent losses of white pines due a number of serious disease and pest problems that are reducing tree numbers. Pests: A […]

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 […]
