Amazing perennials with giant leaves up to 4-8 feet across
This is one of the largest herbaceous perennials in the world growing over 2 meter tall with wider spread. A single leaf can reach 2.5 meter in diameter and are shaped to direct rain water to its roots. Prickly stems. A real show stopper in any garden. Three year old plants are massive, so plan accordingly.Though considered hardy in zone 7, Gunneras grown in zones 7-8 need special care in order to survive winters by cutting down all greenery in late October to 30 cm of the root ball then placeing a thick layer of dry mulch over the crown for the winter. The mulch should be kept dry by a tarp or other rain proofing material. Remove mulch when last spring frost is past.
