While searching for information as to whether the Mexican Hat Coneflowers I sowed last year are perennials in my zone (they are), I happened upon this website which categorizes wildflowers by height, color, zone, etc.

I think this website might help me become a little more organized in what I should wintersow and where I should put my seedlings next spring! :)

Just thought I would share...
