We’ve long loved the fern genus, Pteris (pronounced terrace), but struggled for years to find any that were winter hardy here in Zone 7b. That changed with our 1996 Chinese expedition to Yunnan Province, and later a subsequent expedition by gardening friends to Sichuan Province. On both trips, high elevation collections of Pteris vittata were made that were much more cold hardy than anything from previous introductions. Both introductions have thrive here since the late 1990s. What we also love is that these ferns thrive in full, baking sun. Even now, in mid-July, these ferns look absolutely amazing in the gardens. Plant Delights currently has one of these amazing selections for sale. Hardiness is Zone 7b-10b.
