This particularly vigorous form of the little-known walking maidenhair fern was shared by plantsman Roy Works after we admired it in his Tampa, Florida garden. Although Adiantum caudatum emerges late after a hard winter, it is evergreen in milder climates. Our plants have survived 7 degrees F, to form a 5' wide patch in 5 years. The 1.5" wide x 2' long arching fronds, which emerge pink in spring, root into the ground at their tips, forming new plants. Moist soils result in faster growth, but our plants are quite happy in a fairly dry, sandy soil. Adiantum caudatum is a most unusual plant, sure to get your gardening friends talking.
