Moderate

General Notes

Grows in extensive colonies in shady situations and also in full sun where clumps are extremely dense. Best suited to large gardens or where it can spread. Likes plenty of water. Fronds are sticky in shady situations but much less so if grown in full sun.

Seed Information

Seed Collection

Sori – round to ovate. Collect spores when mature on the frond. Unripe sori are generally light green then change to yellowish-brown and to dark brown or black when mature. Place fronds, or portions of fronds, containing ripe spores in a paper bag and leave in a dry and draught-free place. Spores should begin to release immediately and all spores are released within days unless the species has tough, leathery fronds. Some species produce large quantities of spores from one frond, others require many fronds to produce similar quantities.

Seed Treatment Method

Standard Scatter seed thinly on to damp potting mix. Hold seed in place by covering with more potting mix to approximately the depth of the seed size.

Seed Treatment Notes

Use a moisture-retaining medium and a pot that allows drainage. Sterilise medium and container with boiling water. Sow spores by sprinkling a small amount onto the surface of the medium. Cover immediately with clean glass or plastic wrap. Leave in a warm area in strong, but not direct, sunlight. Specks of green appear after 2-4 weeks. These are the young prothalli. During the next 6-12 months they are at risk from overcrowding and pathogens. When the first fronds appear the sporelings can be slowly hardened by gradual removal of the container cover. Take care to avoid drying out. Prick out sporelings when the second frond appears.

Cutting & Division Information

Can be propagated by division.
