I'm planting dahlias in February mostly because I'm curious how early they'll bloom in my climate (zone 8, SW Washington state). My last frost is mid April, so this week is about 6 weeks before then. I'll be reporting back on how they do and how quickly (or slowly) they grow. And of course when they bloom!
