Echinocereus yavapaiensis - Yard Seed

Echinocereus yavapaiensis is a newer species from central Arizona. This seed was collected from our garden, most plants look pure but hybrids could exist. I checked a few plants and they are hexaploid plants as they are supposed to be, but I couldnt check them all. This plant can be very large if planted in the right conditions with good drainage. These plants have taken -17F in our garden and seem unphased by it. Once the plant reaches dish plate size, they really slow down in growth.
 
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.
