I think these are what are growing along the border of our driveway. They just appeared one year, and have been left to fend for themselves. They produce fruit each year, without feeding or any special watering. They just get on with it.
They are teeny tiny fruits, so I am assuming that they are alpine. I took some runners last year, most of which produced plants, and I'm hoping to grow some in the back garden this year (the plan was the block pave the driveway, so I wanted to try and save the plants - that plan has changed now).
Our front garden gets sun in the mornings and is shady in the afternoons, so they seem adapted to those conditions
