Jim, All my seedheads are independant. Perhaps it's because they live such an upright life. A. triphyllum, A. dracontium, A. tortuosum, A. sikokianum are all upstanding plants. A. ringens, A. speciosum, A. candidissimum, A. franchetianum, A. fraturnum, and the others didn't set seed this year. Ray <GRSJr at Juno.com>
