In studies where cattail litter was added to test sites, native wetland plants such as marsh bellflower (Campanula aparinoides), bulb-bearing water-hemlock (Cicuta bulbifera), and stiff marsh bedstraw (Galium tinctorium) did not emerge. Narrow-leaved cattail (Typha angustifolia) has large energy reserves in its rhizomes that supply new shoots with the necessary energy to push through the litter in the spring.

Typha angustifolia emerges earlier in the spring and grows more rapidly and taller than Typha latifolia, often giving it the competitive advantage in areas where the two species coexist. In test areas, T. angustifolia slowly replaces T. latifolia, except in very shallow water.
