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 trichomanes
