Seed Information

Seed Collection

Seed heads release nuts easily when ripe. Seed is released within 3-14 days of seed maturity, and produced in good quantity.

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.

Seed Treatment Notes

Several months dry storage may be required. Surface sow, or cover lightly. Smoke treatment or leaching may be useful.

Cutting & Division Information

Can be grown from division, but this is labour intensive.
