Holodiscus discolor

At last I have a name for this shrub, which is in Abergavenny's Linda Vista Gardens! Some years back, a judge of Wales in Bloom rhapsodised over the specimen, but I failed to remember what he called it. This year, the Mayor, who was walking a new judge around the town, got his phone out - and wonders of the web, came up with the name. Commonly called creambush.
