This is one of my most favourite troughs.  Amazingly beautiful colouring to the stone.  Lichens.  I have called it a 'Boulder' Trough because it has been carved out of a boulder of limestone.  The base is not flat and it needs leveling because of its characterful nature.  This is a stunning trough.  A D shape of sorts as has a flat back and a rounded corner front.  In great condiion.  Would need careful sealing for water as very craggy inside.  Wonderful planted with a pool in amongst the plants - a large trug or planted fully obviously.  A stunning trough.
