Re: Iris missouriensis

James,
 
I collect missouriensis and have had no problem raising them in acid soil. We live in the NE part of WA state in the foothills of the Selkirk Mts. Huckleberries grow wild here and blueberries can be grown without amending the soil.
 
The majority of my collection was brought from a cattle pasture just north of Odessa, WA (highly alkaline with soil that resembles concrete) and popped into my garden (acid, sandy, and well drained) without any coddling. In fact, most sat on my porch for a couple of days in a bucket till I could figure out where to put them. The rest were brought in both as plants and germinated from seed.
 
The only hard and fast rules I've found are that they germinate best if stratified and if they need to be moved, it's best to do so before bloom. They also seem to prefer slightly poorer soil and less humidity than any of the other iris groups except arils.
