Allow about 18–22 inches for the plant's listed mature height and spread; the catalog's 18–22-inch display range is retained alongside its approximate metric point. ## Maintenance Use the cultivar's series guidance for local growing conditions and avoid keeping the root zone persistently wet. Winter flowering is climate dependent, so plan for the spring display as the dependable season and treat mild-winter bloom as a bonus.
