Fun Facts
Northern Wildrice grows in shallow lakes, ponds, slow-moving rivers, and sheltered wetlands. It has long, narrow, arching leaves and graceful stems that rise above the water. In late summer, it produces loose clusters of flowers and seeds that hang from the upper stems. It prefers shallow, calm water, generally with soft, muddy or silty bottoms. It is best suited to a natural pond, large water garden, wetland restoration project, or shoreline planting rather than a typical garden bed.
Nothern Wildrice must produce and drop seed each year to maintain a population. It does not tolerate strong waves, fast-moving water, or heavily disturbed shorelines. Once established, it can reseed naturally and may form extensive stands. Avoid planting it where water levels fluctuate dramatically during the growing season. Do not fertilize; excessive nutrients can encourage algae and competing aquatic plants. It is not a good choice for a small backyard pond unless the pond has suitable shallow-water habitat and relatively natural conditions.
