| 説明 | Native, warm season, perennial, robust, erect, rhizomatous, emergent aquatic herb to 4 m tall. Thick, strap-like leaf blades are bluish green, and up to 2 m long and 3 cm wide; upper leaves usually have a distinct auricle. Flowerheads consist of a cinnamon to brown cigar-shaped spike of female flowers (10-40 mm diam) that is 0-5 cm below the male flower spike. Flowering is year-round, but principally from late spring to autumn. Widespread in stationary or slow flowing water of drains, creeks, dams and swamps. Less salt tolerant than Typha domingensis. Native biodiversity. Provides important habit for water birds. Stabilises creek banks as the plants trap sediments and slow water flow. Can become a nuisance by clogging irrigation channels and excluding other plant species. Unpalatable to stock except when leaves are newly emerging; emerged leaves are very tough. Can be controlled by cutting below the water line or cutting followed by flooding (most effective in autumn when rhizome energy levels are low, but can also work if repeatedly cut at other times), mechanical removal or spraying with herbicides. Favoured by deep, constant depth water. |
