Plumleaf azalea (Rhododendron prunifolium) has been blooming in my garden for the past ten days. This species is a late July – early August bloomer in northeast TN. The bright orange-red flowers of this native azalea light up any garden spot whether in full sun or partial shade. Provide some additional shade in southern climes […]

Posted by Hugh on July 5th, 2010
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). Coreopsis ‘Route 66’ originated in Pennsylvania (zone 5). Perennial gardeners have been planting yellow- flowered ‘Moonbeam’ and ‘Zagreb’ cultivars for over a quarter of a […]

Posted by Hugh on June 28th, 2010
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 […]

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 […]

Posted by Hugh on April 16th, 2010
‘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. Gomphrena hold up to the wind, blooming from day of planting in May (after […]

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. […]

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 […]

Posted by Hugh on January 22nd, 2010
I recommend adding ferns in your shade garden. Ferns offer very fine textured foliage. Plant’em in clumps of three or more. Select the proper fern by your garden site, e.g whether it is likely dry or moist soils. Some grow surprisingly well in full sun, but most prefer partial to full shade. Don’t buy a […]

Posted by Hugh on January 4th, 2010
The Benary ‘Big Begonia’ series are a hit, “begonias on steroids”, some gardeners may say. Individual flowers are twice that of other bedding begonias. Colors are vivid with three cultivars currently available . ‘Big Rose Bronze Leaf’ is my personal favorite. (pictured) Begonias grow best in well drained, humus-rich garden soil. Provide tender -loving care […]
