Rain Gardens - Suitable for rain gardens and marshy locations. Plants will do well in full sun, but they need a reliable source of moisture. In other words, you need to water them, or they will indeed suffer.
For your Patio - Pot Cardinal Flowers in large pots, then enjoy them on your deck o r patio. You will gradually earn the trust of the local Hummingbird population. For winter storage, either set the decorative pot in a second pot and fill the space with leaves or hull (dig in) into the top of your compost pile in the fall.
Territorial - Hummingbirds are very territorial, I make a point to grow Cardinal Flowers in various gardens. This way there is no fighting!
