I used to visit the Necropolis with my late dad, then later myself when I was at the varsity next door. This in the early eighties. It was the only place I ever found pink bluebells growing, amongst the headstones. And presumably the bulbs are still there? White bluebells were "common" in the extensive bluebell woods of Cumbernauld (my then hometown) but never any pinks except the Necropolis, of all places.
One thing I didn't realise until leaving Scotland is that Glasgow also has a southern necroplis too. Anyone got photographs from there? In particular, I believe Thomas Lipton is buried there, he of tea fame?
