Plant type: Herbaceous perennial
Botanical name: Crambe cordifolia

Features white sprays of flowers on stems dangling over large, deeply lobed basal leaves. Foliage adds a nice, bold texture to the garden. Blooms from late spring to early summer. Plant size ranges from four to seven feet tall and three to four feet wide.

How to use it: In masses or as a specimen plant. Use in a mixed perennial border or cottage garden.

Culture: Prefers a rich, moist, well-drained site. Will suffer in dry soils. Plant in full sun and tolerates part shade. May require staking. Propagated through seed or root cuttings. No serious pest or disease problems; caterpillars may feed on the foliage.
