I have very few yellow water iris seed pods this year. Was going to try and grow some new plants from seed. Would like more seed and some more colors. If someone has water iris and would like to get rid of the seed pods I sure would like some. Now is the time to pick them off your plants. I have yellow and would like blue or any other color. Let me know how much you would want for them. I would also pay for shipping. If I can get these plants growing, I believe they would make good habitat for the fish and help with the bank stabilization. Plants started from seed have a better chance of not bring in some unwanted plants.
I had over a 150 plants put in my pond and between the geese and muskrats I am down to 5 or 6 clumps on one side of my lake.

Yellow are invasive and spread quickly, blue aren't and don't.

I, too, have yellow iris seeds from a client's pond. The yellows have not proven invasive at that location nor at my pond.

My two plants didn't even bloom this year. These two were transplants several years ago, and have not "taken off" yet. I plan to plant some of the client's seeds here, too. My pond is so small, 1/4th acre, that I won't have any real trouble controlling the iris if they ever start to spread.

If anyone has surplus seeds from another color of iris, I'll take some too, after nehunter gets what he wants.

Thanks.

nehunter-- are you doing anything to eliminate the muskrats?? If you do not eliminate the muskrats, I think any attempt to germinate seed or move plants may not end well. I have a small pond- about 1/4 acre- and about 18 months ago a couple 'rats set up shop in the pond banks. The two soon became five or six. The family made quick work of my aquatic plants- first aggressively consuming and destroying the pondweed, then they proceeded to cut down the canes of the YI. I was shocked at how much damage they were capable of in just one overnight period. I managed to exterminate that "family" after a couple of months. The YI will not recover in the season that the damage occurs. The YI did recover- at least most of the plants- the following spring. Not long after the canes got to about 6" tall, another 'rat showed up late winter '20. I set traps and in about six weeks I had trapped four 'rats total this year (and a mink- probably because the muskrats were present). I was fortunate in that I was watching the pond as the ice began melting and observed the muskrat activity. I got them early before they did much damage to the YI shoots this year.

Just sharing my experience with muskrats and YI so you can be prepared for the continued loss of plants if muskrats continue to be present in your BOW. I had a bumper crop of YI seeds this year. (I recently gave quite a few to another PB member actually, so I can't help you this year...) The quantity of seed pods is directly related to the number of blossoms of course. Maybe the critters injured your YI plants to the point that they didn't bloom very well this year??

Anyway, good luck in your search. As esshup pointed out, the YI are invasive due to the seeds. I have plants that have appeared in the swale area that receives the overflow from our pond. I actually like the plants since they do stabilize the swale banks and slow the water velocity. And then there's the bonus of seeing them bloom in early June.

My iris were under water a couple of times when they were blooming. I think this caused them not to put on pods. This fall the coons also smashed them flat. I think they were after the bullfrogs that were in the flowers.
I do have some people trapping but maybe I need to start also.

Well I opened the pods I have and I have over a 100 seeds. If 1/2 of them grow I will have plenty yellow iris. I would still like some other colors. There is a blue and I think there is also a purple water iris, if anyone has these I would love to get some from you.

Be sure folks know this is an exotic invasive plant and may be prohibited in some locations. I have these also, but folks should be aware of this if they are considering this plant. Blue flags are a non-aggressive native.

Should the blue ones be planted in the water or on land?

I plant the blue native iris in 2"-4" of water at or near the high water mark. Native blue iris can withstand pond margin dryness of summer and being covered with 10"-12" of spring time water levels.

I like the yellow iris because it grows 1/2 as tall as cattails. That way there is less plant material to rot in the water. With all the shallow water I have. I have the potential of having 15 to 20 acres of cattails.

I like giant burreed as an alternative to cattails.
