Adenophora General Information

Deadheading will prevent seeding and a barrier will help with running if spread is not wanted. A better choice than Campanula for southern gardens. Idaho has restricted all potted plant material from being shipped into Idaho at this time.

Adenophora Plant Care

To promote bushiness, Adenophora may be cut back by one-half in May when they reach 6-8" tall. Cut plants down to basal foliage in fall, clean up in spring. Long-lived. Roots deeply, so may be difficult to divide.
