Typha minima

The familiar bulrush found beside ponds, lakes and streams, is too large and invasive for all but the largest gardens, but Typha minima is a tiny species with a perfect miniature form. It's ideal for growing in small ponds and even aquatic tubs. Its creeping rhizomes will spread steadily, nonetheless, and it's best confined to a basket. The male flowers appear in summer as small tufts above the familiar bulrush, which is the female flower-spike, and where numerous seeds may form. If this is a problem, plants can be deadheaded, but this will remove the ornamental bulrushes.
