Polypodium californicum or California Polypody
Polypodium californicum or California Polypody is a slow growing native fern that reaches between one and two feet in height, and three feet in width. This slow-growing plant favors the northern facing slopes and spreads via rhizome (an underground stem that puts out lateral shoots). Unlike a commercial fern, this plant can survive with little water, but prefers cooler temperatures and shady areas. These beautiful plants, with their ruffled leaves, can be found growing in and around the boulders on the northern side of the Yawkey Trail - especially during the cool and rainy months.
