Caught between a rock and a hard place

Sometimes we are so intent in trying to look at the bigger picture that we forget the small things. The Weekly Blip Challenge theme of Patterns in Nature seemed like a good reason to go and have a wander around Edinburgh's Botanical Gardens and I found it good for the head to look a little closer at things. This little rockery plant (apparently a Saxifrage longifolia) was only a couple of centimetres across but lodged amongst the rocks it really stood out.
