planting flowering fern from seed

Question

I have harvested seeds from the brown pods of my flowering fern. Should I let them dry longer? when & how do I sow the seeds? How deep? How far apart?
I grow them shaded in afternoon.

I live in zip 95076, in the banana belt or warmer in summer-colder in winter

Thank you

Be sure the seeds are dry before you plant them. Usually mature seeds are brown or black. Your hardy gloxinia (Incarvillea delavayi) grows easily from seed outside in the ground in the fall or spring. They can be grown indoors as well. They need light to germinate so do not cover when planting. Just lightly firm them down on the soil. Water them with a mister so as not to disturb the seed on the soil. If growing inside in pots, use about 3 seeds per pot. Then after germination remove the 2 weakest seedlings. Germination can take two to four weeks, so be patient. If growing outside, leave about 12 inches between plants after thinning to accommodate a full sized plant.
