Broadleaf cattail (Typha latifolia), also known as common cattail, is a perennial wetland plant that forms large, dense colonies through a thick, spreading rhizome. Its upright stems can reach up to 2 metres. The leaves are long, flattened, ribbon-like and straight, about 1 to 2 cm wide. The inflorescence is divided into two distinct parts: a short-lived yellow male spike above a compact dark brown female spike, which persists through winter. It grows in full sun, in shallow water or saturated, nutrient-rich soils, in marshes, ponds and drainage ditches.
Medicinal and culinary uses
The young underground shoots can be eaten raw or cooked as a vegetable. The immature male flower spike, harvested before releasing pollen, can be cooked and has a flavour similar to corn on the cob. The rhizomes, rich in starch, can be dried and ground into flour to thicken food preparations. The pollen is used as a thickener or as an ingredient in baking. The rhizome is astringent and antiseptic, used to treat diarrhea and promote wound healing. The roots and leaves are also employed for their diuretic and anti-inflammatory properties.
Ecological roles
This species actively filters excess nutrients from water, helping reduce eutrophication. Its root system stabilizes shorelines and limits erosion. The persistent female spikes provide nesting material for birds and small mammals. The plant shelters aquatic insects and larvae and serves as a spring food source for various aquatic organisms.
