If you garden in USDA zone 6, certain crape myrtle cultivars are rated as reliably winter hardy perennials. Most dependable are the U.S. National Arboretum cultivars released starting in the 1980’s to date. Each one is named for an Indian tribe.

Serbian spruce (Picea omorika) rises as a tall spire in the urban landscape. A mature tree may reach 50 to 60 feet high and it creates a narrow footprint of 15 to 25 feet wide. Lateral branches uniquely bend downward while the growing tips sweep gracefully upward. Annual growth rate is slow at 12-15 inches. Two-thirds of the short dark green needles lay […]

For sheer toughness ostrich fern (Matteuccia struthiopteris) handles most landscape situations (USDA hardiness zones 2-7a). Ostrich fern is commonly seen growing naturally in cool moist river bottom soils, 3-5 feet in height and spreading aggressively. Roots have a clumping rhizomatous nature. The fronds grow upright with a slightly arching form, typically to 2-3 feet in […]

Morning Grace spiderwort (Tradescantia rosea ‘Morning Grace’) is a short growing spiderwort native from Maryland south to Florida. Its small size and clumping nature makes it a wonderful rock garden plant. It grows into 8″ tall x 8″ wide clump of narrow medium green leaves. At first glance this spiderwort’s foliage appears very grass-like. […]

Architecturally, yucca (Yucca filamentosa), aka Adam’s needle or Spanish bayonet, makes a strong landscape statement. Yucca is often difficult to fit with with other shrubs, except perhaps other xerophytic plants. Yucca is frequently used in an arid-looking or in a courtyard setting in gravel mulch. Yucca prospers in full sun and a well-drained soil. This […]

On a recently trip to the Ohio State University Horticultural Gardens in Columbus, I discovered ‘Lady Frances’, a relatively tame miniature ivy. The American Ivy Society classifies Hedera helix ‘Lady Frances’ as non-invasive, and it received the first “Ivy of the Year” award in 2001. It grows slowly and works as a ground cover or topiary […]

Their leaves (called “fronds”) appear delicate, but maidenhair ferns (Adiantum spp.) are reliable long-lived perennials. Northern maidenhair (A. pedatum) thrives in most gardens within USDA zones 3-8, while the Southern counterpart, (A. capillus-veneris), predominates in warmer USDA 7-10. Unfortunately, planting of maidenhairs are not utilized in the Southern Appalachian gardens (USDA zones 6-8). Fronds average 18-24 inches in […]
