I planted three A. rupestris
plants this
spring...they grew and bloomed beautifully. I am concerned about overwintering them here in
zone 7 because they can be really finicky. I know they need excellent drainage, so I added sand and compost when I planted them. What I need to know is do I cut them back now or wait until
spring, and how far do I cut them back (the base almost looks woody like lavender)? If no one is familiar with it I will probably wait until
spring and see where they start to regrow before I cut them back.
