Broadleaf Arrowhead

Growing

Growing Broadleaf Arrowhead is a rewarding endeavor for those with a pond or a water feature, as this species thrives in environments with constant moisture and can easily tolerate very wet soil. Rather than starting from seed, you will establish this plant by planting tubers, bulbs, or crowns directly into your aquatic setting. Because it is a wetland species, it is best suited for locations where the substrate remains saturated, mimicking its natural habitat in marshes and shallow waters.

When managing your aquatic garden, keep in mind that this plant is often referred to by several names, including wapato, duck potato, or Indian potato. If you are cultivating it for its edible tubers, you are following a long tradition of use by Native Americans. While the foliage is striking, the true interest lies beneath the surface. Ensure your planting area provides the heavy, damp conditions this species requires to develop its characteristic underground structures.
