Clethra barbinervis

Japanese Clethra is waiting to be discovered.  It is a plant for all seasons, boasting fragrant mid summer blossoms, yellow-orange to red fall foliage, and exfoliating bark in winter. If left unpruned it will grow as a multistemmed shrub or small tree, but we prefer to see it trained to a single leader, with lower limbs removed, so that the showy bark can be better appreciated.

We were smitten when our young plant came into bloom in July. Trios of sweetly scented white, 4-6″, twisting racemes will drip from the branches into August. The ovate serrated foliage, in a shade of dark green, really sets off the white blossoms. Fall color is also striking, ranging form yellow orange to deep red. Although Clethra barbinervis is fast growing, it seems to reach an ultimate height of 15-20′. It prefers a well drained, neutral or slightly acidic soil with adequate moisture. Clethra barbinervis grows well in partial shade, although it will tolerate and bloom abundantly in full sun, if watering needs are met. It can be cultivated in zones 5-8.
