Broadleaf Cattail
Typha latifolia
The broadleaf cattail is a perennial herbaceous plant reaching heights of up to three meters, known for its characteristic cylindrical flower spikes. Its grey-green leaves are linear and approximately 10 to 20 millimeters wide. It typically inhabits nutrient-rich standing or slow-moving waters and marshes. A distinguishing feature is that the male and female portions of the flower spike are directly adjacent to each other.
Details
Oxygen production
Low direct contribution to water oxygenation, but transports oxygen via aerenchyma into the root zone.
Habitat function
Serves as cover for fish, spawning substrate, and as an important nesting and hiding habitat for birds like the reed warbler.
Nutrient uptake
Very high; efficient uptake of nitrogen and phosphorus, therefore frequently used in constructed wetlands.
Food source for
Rhizomes provide food for muskrats; pollen serves as a food source for insects.
Human use
Used as insulation material, weaving material for mats and chairs, formerly as stuffing for pillows; rhizomes are edible.
Ecology
Ecological role
Primary producer, provides nesting sites for waterfowl and habitat for numerous aquatic insects and amphibians.
Natural predators
Muskrats (eat rhizomes), various insect larvae and caterpillars (e.g., cattail moth).
Competitor species
Common reed (Phragmites australis), lesser cattail (Typha angustifolia).
Ecosystem service
Water purification through nutrient uptake, shore stabilization, carbon sequestration in marshy soils.
Threats
Destruction of wetlands, excessive drainage of marshes, shoreline reinforcement.
Scientific profile
Profile
Reproduction
Generative via wind pollination and long-distance seed dispersal (anemochory); vegetative via vigorous, creeping rhizomes that can form dense monocultures.
