Hart’s Tongue Fern
Widespread and variable group of rhizomatous ferns, once called spleenwort for alleged medicinal value.

Unlike many other ferns, they need a rest period from late fall to early spring when grown indoors; during that time, reduce watering and withhold fertilizer.Asplenium scolopendrium
