Cardinal Flower is a true showstopper of the native garden, renowned for its intense, fiery red blossoms that are virtually unmatched in the plant world. Standing two to four feet tall, its unbranched spikes of tubular flowers are a primary magnet for ruby-throated hummingbirds, whose long beaks are perfectly adapted for reaching its nectar. This short-lived perennial thrives in full sun to partial shade and requires consistently moist to wet soils, making it a perfect choice for rain gardens, pond edges, or damp low spots. While individual plants may only live a few years, they often self-seed in open, muddy ground to maintain a lasting presence. The brilliant red spikes bloom from mid-summer into early fall, providing a late-season burst of color that is as ecologically valuable as it is visually stunning. It is native to nearly every state in the lower 48, bringing a bold vertical element to any moisture-rich landscape.
