Lobelia cardinalis - Cardinal Flower

  • Cardinal Flower is an beautiful plant for moist garden areas or shores of ponds and streams. Basal leaves develop first follwed by a rising show of scarlet red flowers. Plants with red flowers typically attract hummingbirds; sometimes they also attract Swallowtail butterflies because their compound eyes, unlike those of bees, can detect the color red. Ensure soil stays moist during hot summer spells and sprinkle seeds on raked soil before winter to promote expansion of this plant.
