And now that I've become addicted to them I have tons to share too
Irises are awesome--at first I just started sticking little ones in the darndest places where special little rack garden plants had perished. Now I'm in grave danger of having an iris garden
I imagine someone/somemanys went to great lengths to pull the rocks out of your fields and pile them on the hill for you a long time ago, how nice!
I don't know what the secret is to getting overrun with seedlings of whatever goes to seed--probably something to do with the fact that I don't want a gazzillion volunteers more than anything
Keep trying. Lotsa stuff likes to germinate in the rocks and find a root-run between them. Maybe add some bagged stuff plus grit for a loose topping/keep the competition down/time it right with the rains...something...you'll get some to take.
Definitely, try your buckwheat out there...some salvias, penstemon, lavender, larkspur, dianthus, asters--these all self seed like mad for me in my rock gardens
