My favorite plant for the past few years has been the Haskap or "Honeyberry" (Lonicera Caerulea). It is badass in the sense that it's a fruit shrub that can handle extremely cold temperatures, some say as low as -45 F. It also does well in higher elevations, on berms, open areas, in nearly full shade, in various types of soil etc... It is definitely the fruit shrub of choice in Colorado in my opinion, even though various types of blackberries and raspberries do great here.
I have about 3 or so well established Haskap plants and a bunch of younger ones, including Aurora, Tundra and various hybrid strains. My most established plant is a 4yo Aurora which I have been propagating for a couple years now. Propagation can be a bit tricky but I've had the best results taking cuttings when the sap content is higher, in late winter/early spring.
The berries themselves are packed with nutrients and can have a very sweet taste, especially the lower growing Tundra variety. The Aurora berries are more tart (which I prefer) and savory but still sugary in taste. I can see why this plant is taking off in Canada and I believe it will become more popular in the US as well.
