I whish I could write a positive review on the color alone, but this plant always flops in my garden so it looks more messy than pretty, sadly... And the individual plants are not very dense, they do not fill up to make a nice drift. The flowering period is long enough though.. Why does it flop like that for me? It is in full sun. Normally, plants flop in too much shade or when the soil is too rich, which is definitely not the case there. Could it be too dry or too poor for this one? I am puzzled...

My plants crossed on their own and my resulting plants are cranberry colored not purple like those pictured above.

This is a great substitute for delphinium in hot humid areas. While the delphiniums are dropping dead in my garden, this lobelia looks great in August-Sept with its tall, dark purple spikes.

To keep this plant from dying over the winter, be sure to pull out the old crowns, and do not mulch the rosettes. They are hardy to at least zone 4, if they heave, just push them back in the ground.

I love this plant. I had it growing in its pot in the pond this year - not entirely in the water, just about half the pot submerged, and it looked gorgeous. Being in the pond kept slugs/snails off, too. Will see how we get on next year..
