Bring your own dried Agapanthus flowers.
Instructions: Beginning in September, the flowers will wither and fall, and green seed pods will form where the flowers were. If you leave them on the plant, the seed pods will eventually dry out, as will the stalks. You can cut the stalks any time, even if they are not yet dry. It's best to store them in a dry sunny place - and then when the rain comes, store them anywhere dry. If your neighbors have Agapanthus, you can pass these instructions to them, or you might offer to harvest their wilted flowers so you have more for the event.
People of all ages and abilities welcome.
After Agapanthus flowers are dried, the tubular stalks are light and rigid, and the tufts of the flowers (technically the umbellate inflorescences) are like Velcro, allowing us to construct multi-level free-standing sculptures!
