Acanthus spinosus is a spectacular, very large-leaved, fast-growing herbaceous perennial with a striking architectural presence. Tall spikes of two-tone purple-hooded white flowers, throughout the summer, are pollinated by bees, so this acanthus is a useful addition to the wildlife garden. A plant with a rich, long heritage, acanthus leaves inspired the decorative capitals of corinthian columns in classical architecture.

The enormous (up to 90cm), deeply divided glossy leaves can grow up to a metre long and form impressive clumps. It spreads by means of an underground rhizome. Give it plenty of room to make its statement as a specimen plant.

Thriving in dappled shade, this vigorous herbaceous perennial is ideal for adding height and interest to a mixed border. The blooms are also excellent for flower arrangements, both fresh and dried.
