Autumn Colors Conclude with Callery Pears

  Callery pear (Pyrus calleryana) has been declining in planting popularity. But its scarlet red leaf color is both sensational and reliable every autumn in the Southern Appalachian region (USDA zones 6 and 7).  Most people identify the tree by its cultivar name, e.g. ‘Bradford’, Aristocrat®, ‘Cleveland Select’, ‘Redspire’ pear. There are many other cultivars. Callery pears are tough reliable medium sized trees which […]

European Beech Prefers Cool Climes

European Beech (Fagus sylvatica) is native to the cool temperate regions of Europe. In the U.S. it is more at home in the Northeast, Upper Midwest,  and Northwest regions (USDA Hardiness  Zones 4 to 7) where summers are cool. European beech grows in full sun and moist, well-drained soils, ranging from mildly acidic to low basic. The tree suffers in […]

Making A Case for Mugo Pine

Mugo pine (Pinus mugo) is a slow growing needle evergreen shrub of variable heights ranging from 5 feet to 20 feet and more.

It is winter hardy in USDA zones […]

Virginia Creeper – A Question of Place

Autumn foliage color is upon us in the Southern Appalachian region (USDA zones 6 and 7). On a weekend drive through the Smoky Mountains, vivid red Virginia creeper (Parthenocissus quinquefolia) foliage draped highway fences and tree branches. Virginia creeper foliage peaks 2 to 3 weeks ahead of most woodland trees and shrubs. Lots of gardeners […]

‘Diabolo’ Ninebark Has More Than 9 Lives

  The cultivar Diabolo ninebark (Physocarpus opulifolius ‘Diabolo’) is an aggressive grower. A knowledgeable gardener with a sharp pair of pruners may quickly and easily train Diabolo ninebark into a small tree. Plant a ninebark tree in a large container for multi-seasonal color around your deck or patio. Its common plant name “ninebark” says a lot. […]

October Starts Out With Fall Sunflowers

I thank the person who gave me a native swamp sunflower (Helianthus angustifolia). This long-lived perennial appears to have its own internal clock for blooming around the first day of October. Its long narrow rough-textured leaves average 6 inches in length. The 2-3 inch wide flowers appear first on top of the tall 6 to 7  foot plants, and […]

Franklinia Will Survive If…

Franklinia (Franklinia altamaha) is admittedly a very finicky large shrub or small tree. Pure white, five-petal, 2 ½ – 3 inch camellia-like flowers bloom sporadically from August thru mid-October. Flowers are slightly fragrant. In the fall glossy green leaves gradually transition to blends of red, orange and burgundy hues. Franklinia grows best on an eastern exposure […]

‘Chocolate’ White Snakeroot Is A Better Choice

  White Snakeroot (Eupatorium rugosum) is native to moist woodland areas in most eastern and midwestern states (U.S.). It grows in average, moist, well-drained soil in full sun to light shade. It is a long-lived and an aggressive perennial. ‘Chocolate’ (E. rugosum ‘Chocolate’) earns its namesake for its chocolaty or burgundy tinted foliage. ‘Chocolate’ white […]

‘Slender Silhouette’ Sweetgum…Very Few Gumballs!

Sweetgum (Liquidambar styraciflua) is a medium to large landscape tree, which matures to 65-70 feet in height and 35 feet in spread. To many people it’s called the cursed “gumball” or “ankle twister” tree, not be confused with the fruit balls of the American sycamore or London plane tree (Platanus spp.). Gumball detractors should look […]
