Old-Timey ‘Royal Standard’ Hosta Still Rules

Kingwood Center is a wonderful public garden in Mansfield, Ohio with several top notch beds of hostas. One glorious bed of ‘Royal Standard’ hosta blooms their heads off from mid-August into September. With over 35,000 registered hostas available, why look back at this vintage variety.

‘Kim’s Knee High’ Coneflower For Small Gardens

We are in the midst of an Echinacea revolution. Purple coneflower (Echinacea purpurea) is a popular 5-6 foot tall native perennial commonly planted in meadow and butterfly gardens. Kim Hawkes, former owner of Niche Gardens Nursery in Chapel Hill, N.C. introduced compact growing ‘Kim’s Knee High’  a decade ago.

Hibiscus Sawfly Devastates Plant Foliage

The hibiscus (mallow) sawfly is a devastating pest of hibiscus (Hibiscus moscheutos) and hollyhock (Alcea rosea). The adult sawflies are small, barely a quarter inch long. They are mostly black, except for a yellowish brown spot on their thorax, and their smoky wings. The pale green larvae mature to 1/2 inch in length. The larvae […]

A Canna Lily Revival

                    Depending on where you garden, Canna lily (Canna spp.) is a tropical-looking, herbaceous annual or perennial. Its colorful foliage and long blooming time leaves a huge visual impact. Canna is not reliably winter hardy in the Southern Appalachian region (USDA hardiness zones 6 and 7). […]

Move Over AJ, Here Comes T-Rex

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 Has Long Bloom Life

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 […]

To Grow Crocosmia Or Not?

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 […]

Tough And Reliable Chinese Astilbes

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. Astilbes are very hardy in the Southern Appalachian region (USDA zones 6 and 7). If low maintenance is your goal, try Chinese astilbe (Astilbe chinensis var tacquetii). Their […]

Biltmore Estate and Gardens

  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 […]

Where Can I Buy That?

Let’s face it – rare and unusual plants are not likely for sale at your local garden center. Full service garden centers located in large metropolitan areas may sell one or two.The internet has become the best plant finding source. Some on-line purveyors may carry a rare item, but not sell it in large quantities. High sticker shock may chase you […]
