The south-facing beds, overlooking Llyn Uchaf, are a spectacular use of recycled material. They are mulched with a layer of slate waste from Welsh quarries which not only retains moisture but also deters slugs. Maybe you would like to try this at home!

Notice how the blue and purple tones of the slates harmonise with blue-violet-red flowers and foliage, and brighten the contrast of yellows and oranges.

Keep an eye out for the bumblebees in the Slate Beds. In May 2010, a tree bumblebee was spotted feeding on the geranuims here. This was the furthest west this bee has been recorded – read here for the full story.
