My water iris has developed a large, green seed pod. When and how do I save the seeds to start new plants?

Question

I have several water iris' around my pond but have never attempted to save a seed pod before. But with economic woes here in Michigan, I figure that I could save some money next spring by starting more water plants from seed to share with fellow "ponders" or just expand my own collection.

Answer 1

Just let the pod mature naturally and look for signs of splitting. You can then cut off the pod and collect the seeds.

You can also make new plants by splitting the rootstock.

Answer 2

Wait until the pod turns tan/brown.  Snip it off and cut down the stalk at the water line.  let the pod dry for about 2 weeks and break it open and remove the seeds.  When you are sure the seeds are totally dry, put them in an empty container like an empty plastic medicine container until Spring.  Check the books on water plants for seed propagation at your local library.
