Faucaria bosscheana x Stomatium agninum

Faucaria bosscheana x Stomatium agninum is a strange growing South African Succulent. These are cold hardy to 2F and probably better. It took 2F with no damage and is probably a good trial plant for a zone 6. The plants available are in 2.5" pots. 
 
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.
