GrowthFast

An aquatic plant; it grows best in a moisture-retentive, fertile, humus-rich soil, or in in shallow water, and a position in full sun[1]. Plants can produce large lateral runners which may extend for considerable distances[2]. Horizontal runners or rhizomes, both surface or underground, are constantly active and establish new plants or clumps as far as 20 metres from the parent plant[3]. If not controlled, the plant slowly invades wet bottomland pastures and eliminates forage plants. Periodic mowing appears to be adequate for control of advancing clumps[3]. Growth of uva grass is rapid. Nursery seedlings reached heights of 20, 30 Title Butterflies and Moths in Britain and Europe. Publication Author Carter D.

How long seedlings take to reach maturity and how rapidly suckers grow is unknown. Theoretically, baring catastrophes and invasion and shading by trees, individual plants can endure indefinitely. Culms of Amazon Basin plants produced close to 200 leaves during their lifetimes, having from 19 to 28 living leaves at a time. Unbranched culms die after flowering, but only the branches of branched culms die[3]. A dioecious species, both male and female forms need to be grown if seed is required.
