For nearly half a century, ‘Autumn Joy’ has been the leading “stonecrop” or “live forever” sedum cultivar planted. More than once I’ve heard this saying: “if Autumn Joy won’t grow in your garden, you should try another hobby. ‘T-Rex’ is a terrific new hybrid and ‘Autumn Joy’ is one of its parents. ‘T Rex’ has […]

Torch lily (Kniphofia spp.), aka “red hot poker”, is an easy to grow long-lived perennial from South Africa. Its colorful floral spike (and a little imagination) resembles a fiery torch or sizzling poker, visited often by hummingbirds, bees and butterflies. New cultivars are mostly hybrids and vary in plant height and flower color. Starting in […]

This South African native, also called ‘montbretia”, thrives in full sun in well-drained average garden soil. A richly composted soil tends to boost foliage size and bloom count, but often weakens bloom stems, requiring some staking. Crocosmia may struggle in a wet soggy wintry soil. Established plants are exceptionally summer heat and drought tolerant. Brightly colored […]

Astilbes (also called “false spireas”) are favorite late spring flowering perennials. The Astilbe x arendsii hybrids from Germany are most popular and available at local garden centers.

I have visited the Biltmore Estate on several occasions, but my May visit this year was special. I had the opportunity to interview Parker Andes, Biltmore’s Director of Horticulture, and Bill Alexander, Landscape and Forest Historian. Few properties match the overall grandeur of Biltmore Estate and Gardens in Asheville, North Carolina. Biltmore is a historical perspective of America over […]

Full service garden centers located in large metropolitan areas may sell one or two.The internet has become the best plant finding source.

Speedwells (Veronica spp.) are long-blooming, easy-care perennials. Speedwells are outstanding for their color rich floral candles (spikes).

The small individual 5- pedaled blossoms range in colors from white, pink, blue, and several shades of purple. The floral spikes […]
