This summersweet cultivar is a densely-branched, rounded, suckering deciduous
shrub which typically grows 3-8” tall and features narrow, fluffy,
bottlebrush-like, terminal racemes (2-6’ long) of extremely fragrant,
shell pink flowers which bloom on current growth for approximately 4-6
weeks in July and August. Toothed, ovate-oblong, glossy dark green leaves
(to 4’ long) turn a variable but generally attractive yellow/golden
brown in fall. Flowers give way to dark brown seed capsules which may
persist well into winter. Flowers are very attractive to butterflies and
bees. Somewhat unique among summer-flowering shrubs because of its ability
to produce bloom in shady locations.
No serious insect or disease problems.
Mass or group in lawns, foundation plantings or shrub borders. Good flowering
shrub for shade or woodland gardens. Also appropriate for damp soils along
stream banks or pond/water garden margins. Also may be naturalized in
cottage gardens, wild gardens or naturalized areas.
