Over the past decade heartleaf brunnera (Brunnera macrophylla), aka Siberian Bugloss and Alkanet, has become a popular spring flowering perennial in U.S. and Canadian gardens (USDA plant hardiness zones 3 – 8). Native to Russia brunnera need little care when properly sited. Sprays of tiny blue-petalled /yellow centered forget-me-not flowers explode into a blue haze […]

Posted by Hugh on April 4th, 2014
Crabapples (Malus spp.) get a bad rap! Many gardeners associated them with the old diseased and pest prone varieties planted a half-century ago. Modern cultivars make nice small ornamental trees. The new cultivars exhibit exceptional resistance to five serious diseases of crabapples: apple scab, fire blight, cedar-apple rust, leaf spot and powdery mildew. Three of […]

Giant dogwood (Cornus controversa) is a medium-sized deciduous tree that grows to 35 to 40 feet high (in the wild to 60 feet) in USDA hardiness zones 5 to 7. This Asian native (China and Japan) is cherished for its distinctive horizontal (tiered) branching habit. Giant dogwood prefers an acidic, organically rich, moisture, well-drained soil. […]

On an early late winter’s morn, the frosty appearance from a nearby mountainside may actually be from our native serviceberries (Amelanchier spp.) (USDA hardiness zones 4-9). Serviceberry’s small white blooms frequently signals that winter’s end is near. Flowering may last 7-10 days. Downy serviceberry (A. arborea) and shrubby Allegheny serviceberry (A. laevis) are commonly planted. […]

Posted by Hugh on March 21st, 2014
In The Southeast U.S. most ornamental flowering cherry trees (Prunus spp.) are challenged by summer heat and humidity. ‘Yoshino Cherry’ (Prunus x yedoensis) continues to be the top performer in the group (USDA hardiness zones 5-8). In 1912, the Japanese government gifted the United States 3000 Yoshino flowering cherries. In the years that followed, Yoshino […]

Japanese pieris (Pieris japonica) offers a year-round show in a garden with evergreen foliage and showy bell-shaped blooms (USDA hardiness zones 5- 8). New spring foliage starts out bronze-colored and matures to dark green. Attractive, pendulous branches if ivory white flower appears in early spring.

Some non-hardy shrubs can be treated as hardy perennials. Crape myrtles (Lagerstroemia indica) and chastetree (Vitex agnus-castus) may emerge in poor condition after an unusually cold winter. Shrubs like butterfly bush (Buddleia spp.), and blue mist (Caryopteris spp.) often emerge in a ragged state, but recover quicker if cutback near the ground several weeks before […]

Japanese pachysandra (Pachysandra terminalis) is a popular ground cover for partly shaded landscape areas. Our native pachsandra, called Allegheny spurge (P. procumbens), is less known and utilized. The glossy dark evergreen leaves are wider than Japanese pachysandra. Clusters of white bottlebrush flowers emerge 2-4 inches high in early spring; flowers mature pale pink as […]
