Clethra

Summersweet

Just like candles on a birthday cake, the larger, more upright flowers of this superlative Michael Dirr selection are a splendid sight. A glossy late spring flush of tooth-edged leafage in emerald hues sets the stage for the abundant creamy white flowers. Made even more dazzling by their spiced-honey scent, the 6 in. long blooms form nearly horizontal, close-knit cylindrical spires.

In autumn, foliage matures to a pleasing yellow. Strongly vertical, slightly downy brown branches and persistent seed spikes etch winter’s somber landscape. With a compact mounding habit, this Clethra offers a winsome presence in small spaces, and is a choice feature for a patio pot. Give this easy-to-grow shrub moist, slightly acidic soil and, where summers are hot and dry, shade each afternoon.

Blooms late June–July

Size: 2-1/2' high x 3' 0" wide.

Hardy to zone 4.

Our Featured Plant: Geranium nodosum ‘Clos du Coudray’

Gorgeous Geraniums, Long-lasting summer flowers, Saturday Strolls!

Gorgeous Geraniums!

True Geraniums are sturdy yet refined, with 5-petaled flowers borne on dainty stems above attractive, palmately divided leaves. Their spectrum of colors, from cool to electric, is rivaled only by their ability to create soft mounds and flowing carpets of lush foliage in ordinary garden soil. We plant an assortment of cultivars to always have some in bloom from spring to fall. Our hardy selections are easily grown and most will re-bloom after flowering if lightly trimmed. Be sure to browse our online selections.

Enjoy these blossoms all summer long….

Our newsletter features a diverse collection of long-blooming perennials and shrubs whose reliable flowers will grace your garden for months. These lovely blooms unfurl at the beginning of summer and continue flowering through August or September. Offering unique hues, they populate airy sprays, tall spires, blowsy flower heads or bold verticillasters. We hope you’ll find these long-bloomers as delightful as we do. 

Happy digging and happy summer from all us Digging Dog Plant Wranglers!
