PLANT BENEFITS

Cardinal Flower is an important nectar source for hummingbirds and swallowtail butterflies. Most insects find it difficult to navigate the long tubular flowers, so the Cardinal Flower depends on hummingbirds, which feed on the nectar, for pollination. Cardinal Flower is an excellent choice for wetland planting, along the bank of a stream or creek or in a wildflower meadow.


PLANT DETAILS

Cardinal Flower produces intense red blossoms in mid to late summer at a time when many other perennials are fading in the summer heat. Cardinal flowers grow best in a moist location with morning sun and afternoon shade. They need some protection from midday sun, and tend to do well at a wood’s edge or at the base of a tree. Placing them in a low spot in the yard or border to help keep them moist making them a great choice for rain gardens.

The flowering spikes open from the bottom to the top and bloom for several weeks. By the time the flowers at the top of the stalk are open, the older flowers at the base have already set seed. Cardinal Flowers are not true perennials, the flowering stem and its roots die after setting seed, however new offsets grow from the axils of the lowermost leaves and put down their own roots.
