The annual HIPS sale insructions are listed at historiciris.org; just scroll down a bit on main page and click link. By July 13 the irises will be listed with links for pictures. On July 20 members can purchase them, and on July 23 non-members can do that. [But for $10 get an e-membership via the website and get that 3 day "bonus" toward them.] So far there are around 450 varieties to be offered, not all historic ones. Price will be $6.50 each, minimum of 4, shipping to US and Canada included.
If you have extras you have not traded off, the instructions explain how to donate some.
The list of varieties that will be offered in the sale will be on-line later today at historiciris.org. Just scroll down to the sale link. So far it looks like over 650 varieties and over 3600 rhizomes will be offered.
Site is up and running. Lots of moderns as well as historic irises. Most have picture and link to the HIPS gallery or AIS wiki for more detailed description. Shipping is to both Canada and US, but could ask about phyto certificate cost to other countries.
Today Monday is the last day to order specific varieties.
"On Tuesday, we’re starting our Basement Blowout Sale, where you can order grab bags of mixed irises, either in Singles sets (one rhizome of many cultivars) or Clumps sets (several rhizomes of fewer cultivars, for planting in clumps). They’ll be available in set of 25 for $40, 50 for $75, and 100 for $150, shipping included. Great for landscaping! If you want mostly Tall Beardeds or Medians, let us know and we’ll honor that as much as we can; otherwise they’ll be mixed."
