I have grown this plant for several years. I love the color and find it worth the trouble keep it going. Individual plants live only a few years so replacement or propagation is necessary. The plants do really need a lot of moisture so I now have them on the north east side of my house where it is fairly damp. Moisture is more important than sun in my experience. I suggest Conoclinium coelestinum Cori (blue mist plant) as a companion plant, beautiful.

Only 6 of the 15 I ordered from Bluestone survived, but these 6 are sensational. A glorious color; I agree that it's hard to describe! The plants are fresh-looking when the rest of the garden is getting tired, but they begin to flower before the really late perennials ('Autumn Joy,' obedient plant, L. speciosum, etc.). A lot of sun is fine--even better--as long as the soil isn't too dry.

This is my first year with this lobelia, and it is one of my new favorites! I wish I could describe the color - photos don't quite do it justice. It is a very dark fuschia-maroon color - very unusual! It is not, however, so "red" that it detracts from the other flowers in the bed - it compliments the other colors. AND the hummingbirds love it!
