Plant Data Sheet
Species : Cheilanthes gracillima, Lace Lip Fern
Climate, elevation: Hardy to -25°C, USDA Zone 5.
Local occurrence: Counties of
Habitat preferences: Cliffs and rocky slopes, usually on igneous substrates: In drier areas in cliff crevices
Plant strategy type/successional stage: growth stage forb/herb
Associated species: Closest to C. tomentosa, but less divided and sparsely hairy on the upper blade surface.
May be collected as: After ripening and releasing their spores, the sporangia look fuzzy and slightly pale. Ripe sporangia have the most intense color and look firm or very slightly fuzzy. Place a portion of the fern frond having ripe sporangia in a loosely closed white paper mailing envelope and let dry at room temperature for about 2 days. Sporangia is brown to black or gray. Spores are viable for a year or more. Their viability can be extended by keeping the spores in the refrigerator (about 40ºF).
Collection restrictions or guidelines: Sporulating summer--fall
Seed germination: Sow into prepared soil. Gametophytes (prothallia) first appear usually in 2 to 4 weeks.
Seed life:short life, need to be sowed within a few days of gathering
Soil or medium requirements: use a 50-50 mixture, by dry uncompressed volume, of Canadian peat moss (sometimes sieved through 1/8th inch screen) and washed sand having 1/16th inch grain size. Crushed perlite of the same size can be substituted for sand. Perlite has some advantages: it holds water, it reflects light, it might have less contaminants than sand and it usually crushes instead of denting or scratching.
Installation form: Plant fronds when viable
Care requirements after installed: If the sowing container is sealed, no watering is necessary.. If watering is necessary, mist with distilled water; or if growth is yellow, add 1/4 strength nitrogen rich fertilizer. Gametophytes (prothallia) first appear usually in 2 to 4 weeks. The first fronds (sporophytes) appear about 6 to 12 weeks later (up to a year later for some species). Since fern fertilization requires liquid water, Mist with distilled water when the gametophytes are about 1/8th inch across.
