Autumn is a good time to look for fertile fronds and collect spores of ferns. Simply cut a frond with ripe sori beneath and place between two sheets of paper (I use paper clips to hold these together). If the spores are ripe they will be quickly released as the frond dries out, often leaving a beautiful pattern on the paper. This is an example of Polystichum acrostichoides which unusually has sori longitudinally positioned along the pinnae. I aim to collect spores from a range of other ferns and show sowing these and the results later on, though I am sure there are members with considerably greater experience of growing these fascinating plants.
