We Love 12 Black Flowers

Hollyhock ‘Blacknight’

Hollyhocks, Alcea rosea, stand tall in any garden, with flower spikes growing up to six feet tall. ‘Blackknight‘ and ‘Nigra’ are two varieties with almost black, single-petal flowers.

This perennial flower, hardy in U.S. Department of Agriculture Plant Hardiness Zones 3 through 9, prefers full sun and well-drained soil. Once established, hollyhocks can tolerate some periods of dryness. Stake them in windy areas to keep them from falling over just as they bloom.
