Bomarea edulis (aka hirtella)
A fabulous species - basically a climbing Alstroemeria with umbels of bell-shaped flowers on and off through the summer until the frost. In autumn, the green fruits split to reveal bright orange seeds.
Possibly the hardiest Bomarea – the parent plant has gone from strength to strength completely unprotected in our semi shady woodsy raised bed, climbing through a dwarf Prunus. A stunning herbaceous climber to about 6ft.
A more delicately built species with coral pink flowers on twining stems. I've not tried it outside yet but it should be hardy enough in a sheltered spot with the tubers planted deep.
