This was one of the small courtyard gardens at Barnsdale which I particularly liked. I do like formality in a garden to a certain extent, but the planting inside the formality needs to be 'floofy' (one of my technical terms meaning informal and exuberant).
This is a close up of the gorgeous tulips. The colour contrast of the tulips against the green topiary was striking.
The blue of the forget-me-nots seems to cool the tulips down, but this was in a shadier part of the gardens. The colour combination still works really well.
