Answer: There are many heat tolerant perennials that you could plant. Monarda, (Bee Balm), Rudbeckia (Black-eyed Susan), Phlox, Perennial Salvia, just to name a few. As for your hanging baskets, in the scorching conditions that you describe, any annual will need a lot of extra water. The plants that you have tried should do o.k. with a little extra attention ( i.e.; WATER!). If you are just sick of the same old thing though, try verbena, lantana, Black-eyed Susan vine (Thunbergia alata), or lobelia. Goodluck and don't forget the water!
