Camassia cusickii is a bulb that naturalises in full sun to partial shade, throwing up sturdy spires of starry, steel blue flowers. Its folk names include Wild Hyacinth and Quamash. English bluebells are contributing their darker blue blur in the picture above.
The impressionistic look created by the sunlight seems to capture the bounty of the plant. I could have hung about waiting for a cloud to dull the light so I could achieve a flatter effect, but there was so much more to see!
