Arjone patagonica is very similar to Arjona tuberosa and has at times been mistaken for it. The most obvious visual difference is that it is glabrous (Arjona tuberosa is hairy)[].

Propagation

Seed - we have no details for this species but suggest sowing the seed in spring in a greenhouse. When large enough to handle, prick the seedlings out into individual pots and grow them on in the greenhouse for at least their first winter. Plant out in late spring or early summer, after the last expected frosts.
