Welcome to the List! I really can't help you much with dutch iris in
your climate, but I thought I'd let you know how they do here. Our
climate in central California seems practically ideal for them. They
require such low maintenance as do most of the bulbs. I plant in fall
and early winter(still planting). I usually do not dig the required
planting depth recommended as our climate is mild, seldom going below
25F during winter. Below the bulbs I use a mix of compost and garden
soil with some commercial granular fertilizer mixed in. About 2 inches
of this. I cover the bulbs with garden soil. I will give a top
dressing of commercial fertilizer (I use 6-20-20) again in early
spring. And again in the fall after they are established. The bulbs do
not get a bit of water from mid-April thru mid-October. Thats the
climate here. They love it. They come back each year looking better
than the last. I have different kinds, some named others not. One
unknown that is particularly vigorous is a mid-blue, and large. I have
it planted against a fence around the house. Quite dramatic.
I would guess that for your climate drainage would be an important
factor. Try to keep them as dry as you can during the summer. I
remember growing them in Virginia with limited success. Not nearly as
vigorous as here.

hawks, and butterflies.
Temp went down to 30F last night. Coldest night this winter.
