Noteworthy Characteristics
Blunt-lobed cliff fern is a deciduous, Missouri native fern which occurs on rocky bluffs, slopes, cliffs and ledges (often limestone formations) throughout the State. A small, somewhat airy, tufted fern which typically grows 6-9″ tall (less frequently to 15″) and features erect, pinnately divided, light green to gray-green fronds (each with 8-17 pairs of leaflets). Sori appear on the undersides of the leaflets and are covered by lobed indusia. The lowest pair of leaflets have blunt lobes, hence the common name.
Problems
No serious insect or disease problems. Foliage may depreciate in hot summer weather.
Garden Uses
This small fern of rocky ledges and cliffs is ideal for rock gardens. Also effective in shade gardens, woodland gardens or native plant gardens. May be difficult to find in commerce for purchase.
