Echinopsis oxygona, a barrel type cactus with very stubby short thorns.  We've only grown this plant for a couple of years, and only small ones, but we have observed the beautiful and fragrant pink flowers a couple of times now on this safer less thorny cactus family member.  In Pacific Northwest this plant will pretty much always be a container plant.  One-year to two-year plants for sale for five dollars each, three year E. oxygona selling for eight dollars each.  More info coming soon . . .
