Cardinal Flower

Native Wildflower

Cardinal flower is a striking native perennial with upright spikes of bright red flowers that stand out in midsummer to late summer. It is especially effective in rain gardens, streamside plantings, and moist borders.

Why plant it

Few native perennials provide such vivid red color in the garden, making it a strong focal plant. It is also highly valuable in pollinator landscapes, particularly where soils stay consistently moist.

How to grow it

Plant cardinal flower in full sun where soil remains evenly moist, or in part shade in hotter regions. It prefers rich, moisture-retentive soil and is not well suited to dry sites. Water regularly and do not allow the root zone to dry out for long, especially during summer. It is generally hardy in USDA Zones 3 through 9.

Wildlife it supports

Hummingbirds are especially attracted to the tubular red flowers. Bees and butterflies may also visit, and the plant contributes seasonal cover in moist planting areas.

Tips

Mulch can help conserve moisture and moderate soil temperature around the roots. Because it may self-sow in favorable sites, leave some seedheads in place if you want natural replenishment.
