| It would be well worth the try, some places list Anise Hyssop at z4. Even if those plants die, they should give you abundant seedlings next spring to the point of weedyness, and will flower the 1st year. I bet the seed plants will do OK, they are tough natives although short lived (2-3 years). I never ever lose 1st year plants here in z5 (outside Chicago). Here’s a page from Trudi D on how to collect seed if you wish. |
