Hello Master Gardener!
I bought what is labeled as agastache foeniculum from Bachman's and Minnesota Native Landscapes. The two look a little different, and a friend told me that A. foeniculum and A. rugosa are often mixed up. Can you help me identify which is which? Let me know if you have questions or need more information. Thank you!
Hennepin County Minnesota
