Pulmonarias: Wonderful In The Shade Garden

Although my multi-year addiction for hostas has never waned,  I remain equally passionate about the lungworts (Pulmonaria spp.). Lungwort is also called Bethlehem sage and Jerusalem sage. Their uniquely splotched or variegated foliage wakes up a dark patch in any shade garden. Lungworts are planted as ground covers and for color accents. In early spring (March), lungworts send up […]

First, not to confuse you, our North American native witchhazel (Hamamelis virginiana) blooms in the fall. Our native vernal witchhazel (H. vernalis) has been flowering for the past few weeks. In February, the showiest witchhazels are opening now – species from China, Korea and Japan. Two of the very best are a Chinese species/cultivar called […]

Growing Blueberries

Both the highbush and rabbiteye blueberry (Vaccinium spp.) are hardy in the Southern Appalachian region (zone 6-b to 7-a). A hot summer is a nemesis for highbush and an extremely cold winter limits where you can grow rabbiteye within zone 6-b. Blueberry bushes grow 8-15-feet tall, requiring annual pruning.

‘Bosque’ Lacebark Elm – a Better Choice

Recent storm damage has caused a re-evaluation, whether to continue to plant the cultivar Allee®, also called ‘Emerald Vase’. Urban foresters around the state of Tennessee report that limb breakage and clean up around Allee elms is greater than around other cultivars. Bosque seemed to fare much better. Lacebark elm (Ulmus parvifolia) is a beautiful […]

‘Sky Pencil Holly vs ‘Dee Runk’ Boxwood

Boxwoods and hollies are mainline evergreen shrubs, utilized for low hedging, privacy barriers. Single shrubs are planted solely for their architectural accent.  Both hollies and boxwoods grow best in moist, well-drained soils and in full sun to partial shade.  Both prefer soils with a pH of slightly acidic to slightly alkaline.

Keep Your Pansy Faces Smiling

Success in blooming pansies and violas in the winter season depends on two key factors: date of fall planting and soil nutrition.

Five disease resistant varieties of  flowering dogwood (Cornus florida), released by the University of Tennessee in Knoxville, are available at local garden centers this spring.

Hardy Forms of Deodara Cedar

I am surprised by the increasing numbers of deodara cedars (Cedrus deodara) that are prospering in Zones 6-b and 7 gardens. Apparently, deodara cedars are much hardier than once thought. The buzz at a recent American Conifer Regional meeting is these varieties list here are worthy of planting: Tree forms: ‘Karl Fuchs’ ‘Shalimar’ ‘Eisregen’ ‘Eiswinter’ ‘Polar […]
