Hablitzia tamnoides: 10-15’ high x 1 wide / full sun to deep shade / zone 4
Once established, this is a hugely productive climbing vine with a history of edible use in parts of Scandanavia, recently brought to light by edible plant explorer Stephen Barstow. The shoots in the spring can be eaten fresh or cooked, and the mature leaves can be used as a substitute for spinach in any cooked dish you can dream up. It needs a trellis or a bush or tree to climb, and it’s more productive in full sun. Ours are young yet, but we’ve planted them next to an apple tree so they’ll have a good trunk to clamour up.
