Let the Garden Grow

Years ago, after we moved in, we emptied the flower beds in the back and decided on a planting scheme. This Blip concerns the very narrow bed you can see on the top of the wall here.
Over the years I've bought many plants for this bed and all have died.  But these little yellow flowers have gradually taken over the bed,  on their own so I'm letting them get on with it. Research  tells me its a dwarf St Johns Wort (Hypericum olympicum)  which some might regard as a weed. But its not a weed to me - its very welcome.
