While marshes are usually avoided by many of us as mosquito-ridden, impossible to walk in places, who doesn’t know the ubiquitous cattail with its iconic fuzzy brown bob or ‘cat tail’? Most marshes harbor this common plant. We see their brown bobs along highway ditches, in spreading wetlands and forest edges and meadows, on swales of empty lots. But, for something so common, they are rather uncommon and unique. For starters, did you know that the entire plant is edible? Naturalist author and forager Euell Gibbons called the cattail “the supermarket of the swamp.”

Defining Cattails

Even though cattails (Typha spp.) have round stems like a rush (“sedges have edges and rushes are round” my ecologist friend Anne once said to me) and are often called “bulrushes”, they are not a true rush. While both are tall wetland plants, true rushes belong to the Juncaceae family with round leafless stems. Cattails belong to the Typhaceae family and—while their stems are round—have flat grass-like leaves. True rushes (Juncus) have small, often pink flowers with six tepals, with stamens and pistil arranged inside, arranged in whorls of three; cattails have furry, cigar-shaped brown/tan female and male flowering spikes.

While there are several species of Typha in Canada, the most common is Typha latifolia, the Broadleaf Cattail. The next most common is the Narrowleaf Cattail (T. angustifolia), which has more narrow leaves and a narrower fruiting head; it can be easily distinguished by the narrow gap between the male and the female flower clusters.

Range & Habitat of Cattails

.

Cattails commonly occur in all kinds of wetlands, thriving particularly in freshwater of temperate and cold regions. Considered an aquatic or semi-aquatic plant, Typha latifolia is a perennial and uses creeping tuber-like roots or rhizomes to spread into dense stands in shallow water.

.

.

Cattail marshes provide good habitat for red-winged blackbirds that feed on the flowers and build their nests on the cattail plants. Beavers and muskrats like to chew on the young shoots, building their nests with the remainder of the stems. Fish and frogs use the roots to hide or lay their eggs. Ducks like to forage and hide among the tall shoots.

Cattails & Phytoremediation

.

As with most marsh plants, cattails are natural biofilters that absorb, store, and break down harmful contaminants in aquatic systems. Cattails absorb excess nutrients (such as nitrogen and phosphorus responsible for algal blooms), heavy metals (e.g. arsenic, lead, and cadmium) and other contaminants from the water. Through their dense stalk/root networks, cattails trap suspended sediment and help neutralize pharmaceuticals, salts, and even explosive residues. Their roots release oxygen into the surrounding mud, promoting a thriving environment for microorganisms that digest organic waste.

Because of this, cattails are often used in phytoremediation—the use of plants to remove and control environmental pollutants. Cattails are highly resilient plants that can thrive in heavily degraded wetlands, storm water ponds, and industrial runoff areas. This is why they occur just about everywhere, including urban and other disturbed environments. Given that cattails do not destroy heavy metals or phosphorus they take in (they just store them), they must be harvested and removed before they release the contaminants back into the ecosystem once they die.

Given the cattail’s ability to absorb contaminants, foragers of cattails for food should be aware of the environment the cattail is growing in.

Cattail Sexual and Asexual Reproduction

.

Typha latifolia reproduces sexually—through specialized unisexual flowers—and asexually through underground rhizomes. Each plant produces an upright flowering stalk that features male flowers above and female flowers below. This makes the cattail monoecious: both male and female flowers appear on the same plant. The flowering spikes look like two ‘corn dogs’ stacked one over the other.

.

.

The tiny male flowers form a dense inflorescence of pollen-producing stamens above the darker female pistillate inflorescence of ovary-containing flowers. Both flower inflorescences emerge in spring from a green sheath in early spring and resemble fuzzy green spikes.

.

.

Within days, the male flower head turns a tan-colour and flowers are covered in a thick bright yellow powder of pollen. At the slightest agitation of the spike by wind or tap from an animal or insect, pollen flies off, landing on the female flowers beneath—still green.

.

.

Once the male flowers have shed their pollen, they wither and disintegrate; the pollinated female flowers mature from a fuzzy green spike into a dark brown shag resembling a cat’s tail. Thousands of seeds are produced and the puffy shag breaks up into cottony fuzz. Wind and animals, such as birds that feed on the cattail, spread the seeds throughout the wetland.

Foraging & Eating Cattails

.

Young shoots—the tender portion of the leaf cluster— can be simply yanked out of the muck in late spring and be eaten like asparagus. I’m told it tastes like tender, crisp cucumber. The edible portion—the heart—lies inside the outer onion-like peels, which can taste foamy. Forager Chef Alan Borgo uses cooked cattail shoots to garnish a swamp pasta: duck eggs noodles with pollen butter sauce, cattail relish and marigolds.

.

.

Mother Earth News provides a pickled cattail shoot recipe that looks easy to use and is good for almost any vegetable. The sprouts at the tip of the rootstock can be used in salads or boiled and served as greens.

.

.

Both male and female flower spikes can be foraged. The immature flower spikes can be boiled and eaten like corn on the cob They should be gathered in late spring / early summer just as they break out of their papery sheathes when they are still green and tender. Male spikes that have begun to swell with pollen are past their prime. Boil or steam and eat with butter as you would corn on the cob. Shawn Woods of Bushcraft Survival Skills has a good video on foraging and preparing male and female cattail spikes and pollen. Pollen is best harvested from the male flowers in mid-summer and used to make flour.

.

.

Borgo shares that, “Rhizomes are wonderful raw or cooked. They have the subtle cucumber-water chestnut flavor of the hearts, with none of the stringy fibers. They’re crisp, but more tender than a radish, refreshing, and crave-able… I try to do as little as possible to them. Slicing into ¼ inch pieces and tossing with a salad of greens, herbs and smoked trout with olive oil, lemon and herbs is a dish worthy of a five star restaurant.”

.

.

In the fall, the seeds can be harvested from the mature female seed heads and the downy fluff separated from the tiny seeds. Seeds can be used for propagation and the soft down used for lightweight insulation or emergency fire starter.

A last note on cattail’s many uses; leaves and other parts are used as a textile crop for weaving baskets, mats and other things.
