Echinopsis Huascha

Nice flowers! How old is it?

Stunning, aren't they? Not sure about the age - this plant was gifted to me by my partners grandparents about a year ago. It flowered last year too, despite me accidentally breaking the longer section in half. It was broken at a right-angle but was still attached, and I simply propped it up again. A day later, I came to remove the broken part but I couldn't find where it had broken! It had just healed up like a graft would, and then started flowering a few weeks later!
