Ruschia pulvinaris 'Wyoming'
Ruschia pulvinaris is an already cold hardy species of aizoaceae, but this clone is one I call wyoming because it survived -30F in a garden in Wyoming. Im sure it had snow protection but it has proven more hardy just in my garden. So these plants are a single clone grown from cuttings, im not sure if they are self fertile but this is a cutting off the exact plant that took the minus -30F.
I do not guarantee these in a zone 5/6/7 because everyones growing conditions are different but this would be a good trial plant to grow in your cold outdoor garden. Try to plant outdoor 90 days before 1st hard freeze.
