A top performer that is perfect for the late summer garden, Lobelia cardinalis (Cardinal Flower) is a popular, upright, clump-forming perennial boasting a profusion of flower spikes densely packed with brilliant, cardinal red, two-lipped blossoms, 2 in. long (5 cm), from midsummer to early fall. Borne on erect, alternate-leafed stalks rising above a rosette of lance-shaped, glossy bright green leaves, this architectural plant adds vertical interest to the landscape. Extremely hardy, low care, and fairly pest and disease-free, Cardinal Flower tends to be short-lived, although it may self-seed in ideal growing conditions (without becoming invasive)!
