I always plant a large area if zinnias each year. Multi colored and varieties. Im In Georgia and can plant in spring, which after a couple months they begins to look bad and slow blooming and then I replant and those last til frost.
They are easy to grown, look nice, cheap seed to obtain, and I plant them for those reasons plus for my wife to have fresh cut flowers. With that said, I have 7 hives and never seen a bee on them, not even in dearth time.
