where can i buy a london pride plant

They have them at my work so imagine other garden centres would too.

Just about any garden centre or nursery will have for sale

I remember this plant in my grans garden but have yet to see it in any of my local garden centres. the big centres only stock stuff they can shift quickly and I dont think this plant is that popular nowadays(unfortunately). best trying a nursery or mail order

Garden centres round here certainly have ask for Saxifraga umbrosa if you can't see...

its a very common plant north of the border but not down here in the south. you see it in old established gardens but very rarely have i seen it around here for sale moongrower

There's some for sale on Ebay, also Saxifraga x urbium - also known as London Pride.
