Description

Supersized blooms! Vanilla Spice® clethra is a delightful, deer resistant native plant that attracts butterflies and hummingbirds. Glossy dark green leaves set off the pure white summer flowers, which emit a sweet fragrance reminscent of root beer. Selected especially for its extra large flowers - individual florets are roughly double the size of other varieties.

Soil

Grows well in moist and even wet soil though it will tolerate some dryness once established. Prefers soil pH on the acidic side.

Pruning

If pruning is desired, do so in early spring, when the new growth begins to appear on the stems.

Uses

Foundation plantings; mixed borders; wildlife gardens; naturalizing.

Growing Tips

Clethra is a reliable choice for flowering in shaded conditions, though flowering, fragrance, and fall color are all at their best with at least a few hours of sun each day.
