The Q&A Archives: Tell Me About Acanthus Spinosissimus

Question: I was given an Acanthus Spinosissimus and I want to know the following:
1) where to plant, Sun or Shade
2) How tall does it get
3) how much to water
4) Is it an evergreen or does it die back over winter
Thanks, Allan

Answer: Acanthus is a perennial and the leaves will remain during the winter months unless they're subjected to a hard freeze. The plants prefer light afternoon shade but can be planted in full sunshine in cool, coastal areas. Provide regular water during the summer months. Leaves can grow to 2 feet long and flower spikes usually reach 2' in height. Expect the plant to become a 3'-4' mound, topped with tall flower spikes. Clumps can be divided every few years. Hope this answers your questions!
