Walking through a tree fern forest, then a lush swamp of Gunnera as well as alongside traditional borders in a walled garden, Logan Garden’s display is a welcome surprise in the far south-western tip of Scotland. Warmed by the Gulf Stream and with the benefit of plentiful rain, the garden rarely sees frost or extreme heat. The original collection at Logan, established over a hundred years ago, has been expanded with specimens from expeditions to Chile and elsewhere. Lots of plant labels so you know what you are looking at, plus a selection of interesting cakes in the cafe when it’s time to rest up.
