Ideally, you'd want to get them planted before they leaf out. If they've already started, that's ok. Either way, soak the roots in a bucket of water for an hour or two to hydrate them before planting. I don't see any really cold nights coming that would affect the flower buds. I'd go for it, if you can dodge the wind! Happy planting!
