My husband has built a flower box about 15 feet long and 18 inches wide. I want perenial plants, so I won't have to replant every year. We live in central Texas, about 120 miles from Lubbock, Amarillo, Abilene and Wichita Falls.
It's usually hot, dry and windy. Also, is there a perenial flower that attracks hummingbirds?
