Killarney fern  (Trichomanes speciosum)

Perennial: plants that live for at least three seasons; after an initial period they produce flowers once a year.
Vegetative reproduction: type of asexual reproduction (reproduction without recombination of genetic material) that results in the propagation of plants using only the vegetative tissues such as leaves or stems. The resulting plant is genetically identical to the original plant. A well-known example of this is the reproduction of strawberry plants from 'runners'.
