For those of you contributing (or who would like to contribute) to seed exchanges, now is the time to begin collecting iris seeds. Several of the AIS Sections have annual seed exchanges and some are beginning their call for seeds.
To order seeds from the seed exchanges, you do need to be a member of the Section or Cooperating Society; but, you do not have to provide seeds. This can be a great way to grow some unusual or rare irises! Another benefit for joining the AIS Sections and Cooperating Societies.
The Aril Society has just opened their seed exchange to orders. This page has their guidelines and a yearly timeline of activities. You can see the 2013 list and order here.
SIGNA (Species Iris Group of North America) has sent out a call for seeds for their seed exchange which is held in January.
Other seed exchanges are held by the Society for Pacific Coast Native Irises and the Dwarf Iris Society.
