unlike potawie, i have grown goji for 20 years and mine fruit. originally, i would just mow the plants down, they were the result of my neighbour's bush. the goji propagate underground and tunnel everywhere, thus finding a shoot in the middle of my lawn, some 20 feet from the main root and they move fast in the spring. my neighbour use to call them wolfberry and i never thought anything of it, but the shoots grow a good 7 -10 feet in height and as the shoots mature, they get spikey needles much like an orange tree. i find the shoots very weak and damage real easy. last year, i built a new fence and trampled a lot of the shoots, so this year i only got 1 berry, which gave me about 10 seeds. last year, i grew out about 5 seeds to relocate the plant to a different area of my yard, the seedlings grew in their new soil bed but i won't know if the roots actually took until this year. the purple flower they produce is very bell shape and pretty. in about a month or so, i will try to germinate my 10 seeds and see how they fair in dwc. i believe i have posted a picture on this forum in the past.
i don't find the berry sweet, so it depends on your taste buds. in a side by side taste test, i tasted bitter, a friend tasted sweet. i wanted another opinion because of all i have read, saying the berry is sweet - i just don't taste sweet.
there are lots of places in canada to get goji plants, places in quebec and ontario produce plants for resale(richters).
i haven't played with husk cherry or ground cherry but know there are many varieties and last week i saw packaged seeds available, i don't remember if it was stoke seeds or mackenzie.
another berry you may be interested in, is the haskap berry, it is slowly becoming popular as the new super berry. there are a few places in canada propagating them for resale. they appear expensive to start, i think it was 5-7 plants for $50 and you require a propagator plant(male). so a little more work to get started and keep the bush producing. but they are suppose to be quite hardy producing an elongated blueberry type pod.
good luck.
