I have a small patch of Iris's that originally came from my husband's paternal grandmother's garden. We estimate them to be aproximately 75 years old. I am interested in finding out if the pods that grow at the top of the stem, just like the blooms, may be full of seeds. Each pod is about 1.5 inches in diameter x 3 to 4 inches long, and is solid green. There are 6 lines, from end to end, that divide the pod into 6 sections.
Each year my little patch of iris's produces about 30 blooms and 4 to 6 pods. If these pods do contain seeds, when is the best time to plant them?
