Q.Large Stone Urns
I have 2 large stone urns (15/20 litre) and want to plant an interesting evergreen shrub in them – I live in the North of Scotland.
It looks like your region is plant hardiness zone 7 or 8. I do not not know if this location where the urns are is is part sun or shade. 'Interesting' is all according to each person's personal taste, but here are some that I think are pretty neat!
Daphne odora 'Aureomarginata' (zone 7 or 9)

Ribes laurifolium (zone 7 to 8)
Viburnum tinus 'Gwenllian' (zone 7 to 9)
