It grows at a medium rate | and under ideal conditions can be expected to live for approximately 8 years. As an herbaceous perennial | this plant will usually die back to the crown each winter | and will regrow from the base each spring. Be careful not to disturb the crown in late winter when it may not be readily seen!
