100 Seeds Cardinal Flower Lobelia cardinalis Wildflower Perennial

Cardinal Flower is a native wildflower known for its tall spikes of vivid scarlet-red blooms that appear in mid to late summer. Its brilliant color and upright form make it a standout in meadow plantings, rain gardens, and naturalized borders, where it attracts attention with its striking display. This perennial performs reliably in moist settings and returns year after year in suitable climates, reaching its full ornamental value as the season progresses.

Cardinal Flower is well suited to damp meadows, pond edges, woodland openings, and rain garden plantings where consistent moisture is available. The tubular blooms open along tall upright stems above lance-shaped green foliage, creating strong vertical interest from midsummer into early autumn. It pairs nicely with other moisture-loving perennials and grasses in naturalized designs. Provide even moisture during establishment and deadhead spent blooms if desired to encourage continued flowering.
