Cardinal Flower

About this plant

The Cardinal Flower (Lobelia cardinalis) is a showstopping perennial that brings a splash of brilliant scarlet to any garden. Its upright wands of intensely red, tubular flowers appear from mid-summer through early fall, creating a dramatic focal point. Plant in moist locations, such as along stream banks, pond edges, or in rain gardens, where its beauty can truly shine. Beyond its undeniable aesthetic appeal, Cardinal Flower is a vital plant for local ecosystems. Its uniquely shaped flowers are perfectly adapted to attract hummingbirds, which are primary pollinators, providing a spectacular show as these tiny birds dart among the blooms. Butterflies are also frequent visitors, drawn to the nectar-rich blossoms. This robust perennial thrives in partial shade to full sun, provided it receives consistent moisture. It forms attractive clumps of rich green foliage, adding texture even when not in bloom. A relatively low-maintenance plant, Cardinal Flower is an excellent choice for adding vertical interest and a burst of unforgettable color to moist garden areas.
