A top performer that is perfect for the late summer garden, Lobelia cardinalis (Cardinal Flower) is a popular, upright perennial which typically produces a profusion of spikes of large, brilliant, cardinal red flowers on erect, alternate-leafed stalks rising above a rosette of lance-shaped dark green leaves from midsummer to early fall. Quite an architectural plant which 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)!

  • Generally growing 2-4 feet tall (60-120 cm) and spreading 1-2 ft. (30-60 cm), this clump-forming Lobelia thrives in rich, medium to wet soils in full sun to part shade. Appreciates some shade from hot afternoon sun and loves a lot of moisture. Tolerates damp soils and poor drainage!
  • A welcomed addition to beds, borders, wild gardens, butterfly gardens, cottage gardens and near ponds or streams.
  • A magnet for hummingbirds, butterflies and beneficial insects, it is deer and rabbit resistant!
  • Won the prestigious Award of Garden Merit of the Royal Horticultural Society
