The Blue Cardinal Flower (Lobelia siphilitica) is a clumping, perennial wildflower native to North America. It produces deep blue-violet tubular flowers on tall spikes. The foliage is dark green and oval shaped and each flowering stem reaches a height of nearly a metre. An excellent choice for a flower garden, Blue Cardinal Flowers prefer moisture-retentive, humus-rich soil and some afternoon shade. Long-lived, the flowers attract a variety of pollinators, including bees, butterflies and hummingbirds, making them perfect for a wildlife garden. Their striking colour and sweet fragrance make them a beautiful addition to any garden.
