Cardinal Flower

Cardinal Flower

Lobelia cardinalis

Partial sun, wet to moderately wet moisture level, rich soil, slightly acid pH.  2-4 ft. height, blooms in summer, red flowers.  Easy from seed but does not re-seed readily.

Germination Code:  C(60), D

Native Region:  Statewide

Brilliant red flowers that are beloved by hummingbirds.  This plant is a water lover and best with a constant supply of moisture.  Can take full sun if planted in a pond or along a stream bank.  Not long-lived and needs to be divided every 3 years in order to survive.  Roots are very shallow and easy to divide.

    I have tried this plant in part sun in the garden and as a marginal, submerged plant on the edge of my pond. In the pond, it grows as though it is on steroids (5 ft tall) and in the garden it always dies. I can’t seem to keep the ground dependably wet enough to keep it alive.
