Yes - I ignore Zones.
That's me.
Lotsa peeps buy seeds from a MO company and expect they will grow in MO. Lotsa peeps are not as bright as me and many of us here at ATP. It is UNFAIR to them - particularly from a compnay like Baker to not give them fair warning. Particularly when they sell something as a Perennial but neglect to tell you Zone 7 and above. There simply is NO excuse for it. Bakers didn't start yesterday - they are a multi-multi-multi million $ company.
Some other places to check out Johnys Selected Seed and Stokes.
