In my back garden, I filled a narrow bed with strawberries and raspberries (see here). The strawberries here have never done especially well, despite flowering quite well every year. However, the raspberries have been great, and I've discovered that if you leave a couple of last year's stems you get some bonus summer fruit too. Last year I added a loganberry to the middle of this bed, grown as a cutting by my Dad. It didn't do much last year, but now it's covered in flowers, and the bees were loving it today. Once the fruit appear, I'll bring down the netting to keep the birds off, but for now they're doing a great jobs of pest control so they have free access.
