Hart’s Tongue Fern Widespread and variable group of rhizomatous
ferns, once called spleenwort for alleged medicinal value. These
evergreen species resemble one another only in botanical details
and in their need for shade and liberal watering. 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 Native to Europe,
