I have Irises from my Mother's garden. After blooming some of them have a large green bulb like growth on the end of the stalk. What is this? I want to keep these growing healthy since they are all I have from my Mother's garden and she has passed on. They were beautiful this spring and neighbors came by just to see them.
These are the seed pods. You can try saving and planting seeds or remove them to keep your plants nice and healthy.
About two months after pollination, the seed pod will turn brown and split open. Harvest the golden brown seeds in a small paper cup, and allow them to dry out for a couple more months. Keep the cup in a cool, dry place. Be sure to keep the record of the parents with the seed.
In late October plant the seed about 3/4 inch deep and 1 inch apart in well drained soil. Again, label your plantings clearly so that you can identify the sprouts next spring. The planted seed should spend the winter outdoors, planted in full sun.
