We have an island in our church parking lot to care for. I live in Tulsa, Ok., and the island gets very hot. We must give up on flowers now except for the lillies that are already in the ground and lantanas that we have planted. I need something else, and went to Lowe's and bought some of these bushes.

Whatever does not go to the church island will go into my rose garden. I'd like to know which you would choose for the church. We have 4 small plants of each.

Weigela (Midnight Wine) should become 18-24" tall, and 20 - 24" wide. Froebeli Spirea should grow to be4' x4'. The tag says that they are both hardy to -30, but could you tell me about these plants and why I might choose one over the other?

Thanks

Sammy
