Need suggestions

Here in my zone 6b garden, I have tried without luck to grow delphiniums and lupines. The heat and humidity just destroy them...I have yet to have a single one ever return for a second year. I also love foxgloves, but I don't like having to replace them every couple of years. So, does anyone have any suggestions as to what reliably perennial spiked flower I can grow? It needs to be at least 3-5 feet tall.

Hi Alan,

How about liatris, lobelia cardinalis, kniphofia and Lobelia siphilitica? Also, there are several ornamental grasses that get that tall.

When weeding, the best way to make sure you are removing a weed and not a valuable plant is to pull on it. If it comes out of the ground easily, it is a valuable plant.
