Actinidia arguta ('Kiwi Berry')
First time I have seen commercially grown and sold fruit of this kiwifruit species. The fruit of A. arguta have a similar gooseberry-like flavour to the regular kiwifruit Actinidia deliciosa, but without the acid tartness. Lacking the fuzzy skin of A. deliciosa they can be eaten whole. They are pleasant tasting, not outstandingly delicious, but more-ish enough that I could easily stuff my face with them as I can with fresh raspberries or feijoas.
When I worked in New Zealand's Bay of Plenty I attended a demo about HortResearch's Actinidia germplasm collection and breeding work at Te Puke, near Tauranga. They have an amazing collection of wild species there, inluding ones with dense white hair on the skin and one with a deep purple skin like an aubergine.
We were given fruit of A. arguta to try during the presentation; at that stage their selections had not been released for commercial production. I kept one unswallowed in my mouth, and then as soon as I got back to the car I spat it out, kept it and raised plants from the pips, at home! I gave the plants to a local friend when I left the country.
