Many spleenworts are rare. Please do not harvest from the wild. Most spleenworts have very narrow ranges and narrow environmental tolerances. Don't confuse with the invasive tuberous sword fern Nephrolepis cordifolia--if the fern spreads via rhizomes and is abundant, it's probably the sword fern. Retain and treasure if already present. Spleenworts can be used in rock gardens where they grow well on limestone boulders. Many will also do well on logs. A few (such as Asplenium abscissum) can be grown as groundcovers.

Basal rosette has weedy appearance. Roadside plantings or meadow.
