An ongoing series of plant profiles for Louisiana landscapes
Story and Photos by Yvonne Lelong Bordelon
A pond filled with masses of 6-inch blue or purple flower spikes jutting from the attractive green foliage of native pickerelweed is a sight to behold. Among the flowers, you will surely see an assortment of brightly colored butterflies, dragonflies, and bees. You might also observe waterfowl nibbling on the sticky fruits, which contain nutritious seeds.
A wonderful plant for a pond or bog garden, pickerelweed is also used for bio-purification systems because it absorbs nutrients from water and improves water clarity. Good companion plants include white spider lily (Hymenocallis), fragrant waterlily (Nymphaea odorata), lizard’s tail (Saururus cernuus), and powdery thalia (Thalia dealbata).
