Growing
Establishing a cattail patch requires a commitment to saturated ground, as these perennials thrive where water is constant. If you are looking to establish a new wetland area, you can plant from seeds directly into moist soil, though using bare rootstock or container-grown seedlings is much more effective if your site has moving water. Because they are such vigorous growers, it is best to include them as part of a diverse plant community rather than a monoculture to ensure a stable, long-term ecosystem.
Beyond their ornamental value, every part of the plant is edible if harvested at the right stage. When the young shoots are tender, they can be eaten, and the underground rhizomes and lower stems offer a sweet flavor that works well when roasted, baked, or broiled. For a unique kitchen experiment, the bright yellow or green pollen can be used as a substitute for flour in pancakes or biscuits. The starch-rich rhizomes can even be processed into a flour, though this is a much more intensive task.
