Broadleaf arrowhead (Sagittaria latifolia), also known as common arrowhead, is a perennial aquatic plant that forms colonies along rivers, lakes, and wetlands. It stands elegantly above the water with its large, arrow-shaped leaves. In summer, it produces clusters of white flowers with three petals and three green sepals, atop stems that can reach up to 1.2 metres in height. Adapted to aquatic environments, this plant is ideal for pond or stream banks in water gardens.

Sociability index: 2 to 3 → Indicates the plant’s behaviour in space and its interactions with other plants.

Medicinal and Culinary Uses
Broadleaf arrowhead is an edible plant with several consumable parts. Young leaves, shoots, and tender inflorescences can be eaten raw in salads or cooked. However, its tubers, rich in starch, are the most prized part. Once cooked, these tubers have a texture similar to potatoes and can be incorporated into various dishes.

Ecological Roles
Broadleaf arrowhead plays an essential ecological role by supporting wetland biodiversity. Its tubers provide a food source for many aquatic animals, such as ducks, turtles, and various mammals. Additionally, this plant aids in water filtration and oxygenation, helping to remove excess nutrients and impurities. Cultivating the broadleaf arrowhead in aquatic settings supports ecosystem health and stabilizes banks with its robust root system.

 

Upon receipt, it is important to place the packet containing seeds in the refrigerator until sowing.

Broadleaf arrowhead seeds require cold stratification to ensure germination. See the growing notes below for more details.

Growing Notes | Seeds - Broadleaf Arrowhead

Upon receipt, it is important to place the packet containing the broadleaf arrowhead seeds in the refrigerator.

Broadleaf arrowhead grows in full sun or part shade and prefers wet soil.

Broadleaf arrowhead seeds require a 60-day cold and moist stratification period, followed by a 30-day warm stratification period, then a second 60-day cold and moist stratification period to ensure germination.

The broadleaf arrowhead seeds offered by Akène are sold in a sealed bag containing moistened vermiculite. The first stratification period began at the beginning of October. Depending on the month of receipt, they will therefore be at a different stage of the stratification process. Here is the schedule to follow to complete the dormancy cycle:

Early December: take the bag out of the refrigerator and leave it at room temperature, away from light and in its original packaging, for about 30 days for the warm stratification period.

Early January: place the same bag back in the refrigerator for a second cold stratification period of at least 60 days. The seeds are ready to start indoors around the beginning of March. You can also start them outdoors once the risk of frost has passed in your area, keeping the bag in the refrigerator until sowing time. Check the seeds in your refrigerator from time to time to make sure they have not begun to germinate.

Sow the seeds on the soil surface, without covering them, as they require light to germinate. Keep the soil consistently moist but not waterlogged. Germination of this species generally occurs after 2 to 4 weeks.
