Striking yellow flower spikes, green foliage with large leaves; LOVES WATER!! Needs less water in shade than in the sun. Plant in a pond, near a pond or standing water, rain garden, etc; slugs can be a problem; Take a piece of copper wire and tie around the base of the plant and twist. This will create a very mild electrical charge. The slugs will not be able to cross this, and you will not have to reapply.
