If the gardens around town are any indication, I'd bet that Dallas Blooms is starting to look great. I've mostly seen trees in full bloom, and some perennials. If you have a membership, you could go multiple times. I shouldn't talk, though. I don't have a membership, and haven't been there in years. I guess i should go sometime, but I tend to avoid it during Dallas Blooms. Too many people.
