I'm trying to get the best locations for the roses that I've just gotten from Nor'East. I'm toying with putting a Simplex on each side of our mailbox at the street, so all the walkers in the neighborhood can enjoy them, too. This would be in brick planters that go through to the ground underneath the planter. It would be in the hot Oklahoma sun all day, and I'm concerned that might be too much for just about any rose, especially a single mini. Any comments or suggestions? Thanks muchly!!
