Latin Name:
Sagittaria Latifolia

Indian Potato is a wetland plant native to North America with arrow-shaped leaves, white flowers, and potato-like tubers.

Edible Uses

Underground tubers taste somewhere between a sweet potato and yam, with sweet chestnut notes. These tubers have smooth orange-ish flesh and an amazing flavor.  

This native food was a staple food of many Native American groups.  Under the right conditions, it is an incredibly productive species, yielding up to 40 tubers per year from a single healthy plant. The starchy tuber is high in carbohydrates and proteins, low in fats, and contains a variety of vitamins and minerals. The rhizomes, young leaves, and young shoots, and young flowers are also all edible raw or cooked.

Ornamental Qualities

This powerful tuberous plant sends up sturdy shoots of beautiful arrow-shaped leaves in Spring. In Summer, cylindrical flower stalks rise with 2-15 whorls of elegant white, three-petaled flowers, transforming into unique green fruits ripening into Autumn. Indian Potato brings lushness and vibrancy to backyard wetlands, ponds, and water features - a wonderful ornamental landscape addition. Leaves and flower die back in the Fall, and re-emerge each Spring.

Environment and Culture

Indian Potato’s wild home is in ponds, marshes, forest seeps, stream shallows, or similar wet areas throughout North America (standing water less than 12 inches deep). It is often found alongside Cattail, Panicled Bulrush, and other native wetland species. However, Indian Potato doesn’t need to be submerged in order to grow - just kept wet throughout the year.

Indian Potato is also loved by wildlife. Songbirds dine on the seeds; fish and other aquatic life find protection under its leaves, and many creatures enjoy its sweet tubers. In fact, it’s nicknamed “Duck Potato” because waterfowl eat the seeds and try to dive/dig for the tubers (watch out if you have backyard ducks!). And if it’s not grow underwater, gophers or mice are also known to take a nibble...

Harvest, Care, and Preparation

Indian Potato can be allowed to spread and multiply prior to harvest. Sweet tubers are attached to rhizomes around the base of the plant and can be as deep as 12 inches under the soil. Traditional harvesting techniques used one’s feet to detach the tuber from the rhizome after leaves have died down, allowing it to float to the surface, without disturbing the rest of the plant. A pitchfork or rake can also be employed. (In backyard ponds with drain valves, water can be temporarily drained to allow for easy harvest.)

Traditionally, tubers were often sliced and dried, or dried and ground into flour before storing for the Winter. For a simple treat, we recommend cooking adding with oil to a casserole dish (to retain moisture), and then baking at 350 degrees for an hour or until soft (bulbs can be bitter unless cooked). Then, they can be eaten whole, mashed, or sliced and pan-fried. Some like to remove the sprout before cooking, and peel afterwards (up to you).

These potato-like tubers have an amazing flavor and beautiful orange-ish flesh, tasting somewhere between a sweet potato and yam, with sweet chestnut notes.
