I'm not sure if you can help with this plant as you are based in the US. I took this picture today 11th Aug 06, It grows a short hike from my home on the West coast of scotland, about 2 miles south east of Loch Lomond. The plant looks like a shrub, or could be multi branched tree, about 7 - 8 feet tall. It is growing on the edge of deciduous woodland and arable farmland in an over grown hedgrow, about 100 meteres above sea level. The small plums are about 1-1 1/2 cm in size. My mum thinks they could be Damsons but all the pics I have over here dont add up, Ive also looked at Greengages but they don't seem right either. hope you can help. Thanks Karen
