Hi Natalie!
it's so good to 'see' you again!
For sure you should get some eriogonum--there are several low growing garden worthy types and it would be very happy there!
I'm presuming that's a pic of the area you want to plant in? obviously the iris are planted in soil...
You want to add soil to the rocks and essentially create some planting pockets within the rocky parts? is that the idea?
