: It prefers very acidic, thin soil (pH 3.5–5.0) in exposed, often sunny rock fissures. Because it thrives in such hostile conditions where other plants cannot grow, it faces little competition from more aggressive species. Conservation Status
: On the underside of mature fronds, you can find small, rusty-brown clusters called sori, which produce spores between June and December. Unique Hybrid Origins
Bradley's spleenwort is a tufted perennial fern that grows in tight clusters. To identify it, look for these specific features:
: Research suggests that Bradley’s spleenwort has actually "formed" multiple times in different locations from independent hybridization events between its parent species. Habitat and Distribution
Due to its very specific habitat requirements and rare occurrence, it is considered a species of special concern in many states.
: It is listed as endangered in states like Illinois , Indiana, and Pennsylvania, and threatened in Ohio .
: The frond consists of 6 to 14 pairs of triangular, toothed leaflets. The lowest pair are often the largest, and they gradually decrease in size toward the tip.
