I've got a few clumps of these and they vary in shades. One patch always has lots of white ones. I nearly forgot to blip today. I was engrossed in drawing a rainbow picture to put in my window. It was a suggestion by a local mum so that walking with young children could become a rainbow hunt. I was happy to oblige, but my drawing skills are very poor. I had to use a "how to draw a rainbow" tutorial and I only got it right on the second attempt. I hope there aren't any requests for anything more complicated.
