Flowering rush is a rhizomatous perennial that grows on the margins of slow moving waterways. This plant can reach from 1-5 ft. (0.3-1.5 m) in height and can survive in water of up to 9.8 ft. (3 m) deep. The leaves are linear, up to 3.2 ft. (1 m) long and triangular in cross-section. Flowering occurs in June to August, when umbels of small, 3/4-1 in. (1.9-2.5 cm) wide, pink to white flowers develop. Seeds have long beaks, but rarely germinate. This plant spreads mostly from rhizomes and occurs in wet areas with muddy soil, such as marshlands, lakes and streams. Flowering rush is native to Eurasia and was first found in the United States in 1918. |
