Acanthus mollis is naturally found in south-western Europe from Portugal to the Balkans growing in woodlands commonly on stony hillsides.

It prefers a deep well drained organic rich moist sandy to clay soil with a pH range from 5.1 to 7.5 and grows in a semi shaded to sunny wind protected position and is drought and frost tender.

The Oyster Plant is grown for its flowers and clumping habit. It is used along front borders in parks and gardens or is grown in a shaded rockery. It is also grown in patio pots and planter boxes and used around water features for its lush appearance. It establishes from division in 1 to 2 years and is suitable for coastal or mountainous regions. The fresh or dried flowers are used in floral arrangements. ID 59
