Acanthus species and cultivars look magnificent and I grew A. spinosissimus in Zone 5, where, after 3 years, it was showing ominous signs of breaking loose. In Greece, I visited the grounds of a monastary where the ground was entirely covered by Acanthus, and I am speaking of large acreage here. Think twice, and then think again!
I used to have this plant in my backyard in Berkeley, CA. It took me forever to try to get rid of it. To me it looks like a plant from another planet; oversized, overshiny, just too much. It reproduces from rhizomes (??) so even if you dig it up it keeps coming up from every little piece of root you left in the ground. Think hard before planting this because it WILL be with you forever!
Region: Pacific Northwest
Statuesque large glossy leaves that spread to form a formidible clump over time. The reward of proper placement is large spires (up to five feet tall!) of purple and white hooded flowers. Place in a container in the garden for that visual statement. Be warned, this plant will spread under the right conditions. Resist movement as any roots left behind will be new plants the following season.
I love the brilliant rich green color of this plant .What a grate combination with other colorful plants this would make.
