Propagation Method
Seed Information
Seed Collection
Propagates easily from fresh seed.
Seed Treatment Method
Bog Method The seeds of many wetland species need to be kept wet to germinate. Punch a hole in the side of a recycled polyfoam box so that it holds water to the required depth. Sit the tubes in the box to germinate. Once germinated, punch holes in the bottom of the box to allow drainage.
Cutting & Division Information
Propagates easily by division of the rootstock.
