I've had my lone Flame Acanthus since '09 when I purchased it at the Texas Discovery Garden's plant sale -- this is the first year it has thrived.
So . . . shape/pruning-wise, how do you take care of it?
* do you cut it back in the fall/winter?
* do you snip it lightly to help it produce new growth?
* do you leave it alone & let it do its thing?
