Our arugula salad plants are blooming, and the petals look almost like tiny butterfly wings with their dark veins... tiny but beautiful - I really like them - and from what I can tell the bees and the hover flies really like them very much as well :-).
In real life the flowers are a bright lemony yellow colour, but I desaturated the colours a bit to make the dark veins stand out a bit more, and if you are wondering where the stem is at, then I stuck this single flower to our kitchen table top with a tiny piece of chewing gum - it's just a bit of photographer's troubleshooting, right? :-).
