Most of the gardens I work at have gorgeous pools. So the plantings around the pool need to bloom during the summer when everyone is lounging around sunning themselves if not actually n the water.
Hydrangeas are a no-brainer for this, but a tad too sweet, so I always tried to add some hot colors and the daylilies did that job nicely. I do remember one gal asked me to have flowers all around the pool all summer, but none that attracted bees. Hmmmmm. I guess they don't get it. That a flower's job is to attract bees to pollinate them.
