This may be the plant I need for a partly sunny raised bed I just built. Do they flower all or most of the summer? I'm in Indiana -- zone 5. Getting 4 hours of strong sun where I want to plant.

Someone told me that they are perennial but not sure about that -- did hear that they will reseed though and come up every year?

Can anyone recommend a good mix of varieties for a group planting of snapdragons only?

thanks
