How to grow cinnamon fern

When to plant cinnamon fern

Cinnamon fern is a moisture-loving fern whose fertile, cinnamon-brown spore fronds appear in early spring as the fiddleheads emerge. Set out new plants in spring; it is slow to establish but long-lived and may go dormant if the soil dries out.

Cinnamon Fern is timed by season rather than your frost dates, so the planting calendar does not generate ZIP-specific dates for it. Check the cited sources below to fine-tune for your area.
