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 […]

Comments Off on Culver’s Root (Veronicastrum)New Hardier Gardenias
Posted by Hugh on June 18th, 2010
Old fashioned gardenias or cape jasmines (Gardenia jasminoides) are reliably hardy in USDA zones 7-b and 8. Plants require immediate protection when the outdoor temperatures dip below 15 to 20 degrees. The new hardier cultivars are compact growers, 2-4 feet tall and 3-4 feet wide. ‘Frost Proof’, Crown Jewel™, and Heaven Scent™ are three promising […]

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). It blooms over most of the summer, from June thru late August. Its 12-18 inch long blue-violet flower spikes exude a slight herbal fragrance. ‘Shoal Creek’ is a […]

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 […]

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 […]

‘Fireworks’ gomphrena was a sensation in the University of Tennessee Gardens at both the Knoxville and Jackson locations in 2009. Gomphrena (globe amaranth) is a great summer annual that asks for very little care. It is heat, humidity and drought tolerant.

Posted by Hugh on March 6th, 2010
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 […]

All are worthy for planting in your landscape in full sun except where noted. All attract birds and other wildlife to […]
