Lobelia cardinalis, commonly called cardinal flower is a native perennial which typically grows in moist locations along streams, sloughs, springs, swamps and in low wooded areas. A somewhat short-lived, clump-forming perennial which features erect, terminal spikes (racemes) of large, cardinal red flowers. Tubular flowers are 2-lipped, with a late summer bloom period. Flowers are very attractive to butterflies and hummingbirds, but not cardinals. White and rose colored forms are also known.
Easily grown in rich, medium to wet soils in full sun to part shade. Needs constant moisture. Tolerates brief flooding. Soils should never be allowed to dry out. Tolerates full sun in northern climates, but appreciates part afternoon shade in hot summer climates. Root mulch should be applied in cold winter climates to protect the root system and to prevent root heaving. Mulch will also help retain soil moisture.
