Lovely white blooms all summer long! White Pickerel Rush (Pontederia Cordata) grows 24-30" tall and 24" wide, very easy grower! Lovely green foliage with white, flower spikes. Always a mainstay in the water garden world.
Plant in heavy loam soil with up to 6" of water above the roots. Full sun to part shade. Plant in extra wide container (2 gallon or larger) as this is a vigorous grower! Looks great in the shallow end of your pond!
