Rubus illecebrosus

Surprisingly large and slightly semi-doubled flowers for a raspberry. It's made a knee-high patch under an apple tree and needs to be moved somewhere where it won't keep scratching me up. So far it hasn't been willing to make any fruit - maybe it's not self-compatible? I did get its pollen to set a fruit on 'Anne' yellow raspberry two years ago but never got the seeds to germinate. I'd like to try it again though, because it looks like this species might have a very high druplet count (from the looks of the little green parts in the centers) which could make for very big berries.
