Mystery cane fruit
I have a mystery cane fruit (Rubus species) coming up in my garden.
It came up out of nowhere last year, and looks quite unlike the raspberries or loganberries I am growing, and also quite unlike any sort of wild bramble.
I was wondering it anyone could help me identify it. It grows individual canes (unlike the sprawling mass of wild brambles), the canes all come from a single base (rather than spreading underground like raspberries do), and the canes are densely covered in short, sharp spines (it's definitely not a wineberry, though. The spines are less bristly and more thorny than that). These spines are red when the shoots are young, but fade in colour as the cane matures.
I'll hopefully find out when it fruits in a few months, anyway (it's in flower now; the flowers looks just like the flowers of the loganberry near it), but it would be nice to identify it before that, especially as a lot of hybrid berry fruit look the same, anyway, so it might be hard to tell even when it does fruit.
It's wild raspberry, it springs up everywhere here, probably dropped by birds originally, the fruit is good to eat if you want to leave a few.
It could be from the loganberry, or a blackberry. If it's flowering it would be alright.
