Timing shifts with your zone — the Genie can pin down exact dates for you.
How to care for it
Sow or divide in spring or fall; it asks nothing after that. Chop and drop the whole plant where you want potassium — it resprouts within weeks.
Good companions
Insectary plant for orchards and vegetable borders
