Coreopsis ‘Route 66’ – A Riot of Color

 Create a hot splash in your garden this summer. Threadleaf coreopsis (Coreopsis verticillata) ‘Route 66’ is a new selection by Itsaul Nursery in Atlanta, Georgia (USDA zone 4 to 9).

Culver’s Root (Veronicastrum)

Midwest native Culver’s root (Veronicastrum virginicum) starts the summer flowering season in my perennial garden. It naturally grows in open woods and meadows and thrives in fertile to moist soils. However, this deep rooted plant hasn’t complain about the current dry period in the Southern Appalachian region (USDA zones 6-7). Be aware that culver’s root […]

Vitex ‘Shoal Creek’

Chastetree (Vitex agnus-castus) is an 8-10 foot deciduous shrub or 12-15 foot tall small tree (hardiness zone 6-b thru 8). Branching habit is dense and vase-shaped (upright).

Catalpa Both Loved And Hated

Northern catalpa or Indian cigar tree (Catalpa speciosa) has enormous presence in any landscape setting (USDA hardiness zones 4-8). Finding a 70 – 80 foot tree with a massive trunk and thick sinuous limbs is not unusual from Ohio south thru Tennessee. In summer its huge heart –shaped, pale green leaves may be easily reach […]

Growing Tomatoes in Containers

Apartment renters and townhouse and condominium owners till the soil in containers on their patio and deck. For containers the shorter growing determinate type tomatoes are a better choice. Spread out the harvest interval, by not planting all your tomatoes at one time. Start your last tomatoes from seed for June planting and harvest beginning […]

Alternatives to Italian Cypress

  Those of us who live north of Atlanta, GA (USDA zone 7-b) can not enjoy Italian cypress (Cupressus sempervirens), which are not hardy in most of the Southern Appalachian region (zone 6-a to 7-a). If you are designing a Mediterranean look in your garden, choose among select cultivars of these columnar evergreen shrubs: Japanese […]

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. Its dark green foliage turns brilliant […]

Lo and Behold ‘Blue Chip’ Buddleia Is Late Summer Gem

photo taken at JC Raulston Arboretum in Raleigh, NC in June 2009 Lo & Behold® ‘Blue Chip’ is a very dwarf butterfly bush (buddleia) for the summer garden. Its compact 3 x 4 foot height and width is an excellent choice planted in a garden bed or in a container on a sunny patio deck or patio. […]

Aucuba — Major Shade Garden Shrub

On a recent trip to the Knoxville Botanical Garden, I was re-introduced to a plant not used as much as it should be – gold dust shrub (Aucuba japonica). Hardy to USDA hardiness zones 6b-10, aucuba prefers a partial sun to heavy shaded area of the garden. Direct sunlight, even in the mostly cloudy winter may scorch some leaves. Over the past 20 years […]

‘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 […]
