Just stake them, that what I always did.

Thank you! I wondered if I had planted them too shallow but I replanted some of them and they still fell over.

My Cardinal Flower always get eaten my the bunnies

Yes, use some type of stake. I think they like some shade and a moist area to thrive. I have never been successful with them here in Florida. Our soil tends to be sandy and it's not easy to find consistently moist soil in many places, although I guess areas near swamps or lakes would be best. I'm on top of a sand hill. From what others have said in hummingbird forums they are excellent hummer plants.

I am keeping mine well watered in this extremely hot and humid summer we're experiencing in the north east; I think they get sufficient shade and we did bring in good soil before I planted them. Yes, the humming birds love them! I planted them near our porch where we can see them at mealtimes, and watch the many and varied birds feeding. This year the humming birds are very active.

Regarding the hungry bunnies, we ended up in trapping 3 groundhogs which were devouring certain plants in both my flower and herb garden (they particularly like cilantro!); we released them into the wild many miles from here.
