I have three trees, two had fruit which stayed hard for ages and then some of it just shrivelled up, one tree didn't fruit at all. Did get enough to make damson gin and a batch of jam, so judging from the comments above, it looks like I had a pretty good crop as far as 2012 goes. Here's hoping for a bumper harvest in 2013 (and a summer would be nice too while we're at it).
