Summersweet

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.
