In the Dandelion Archive I have a sample of lovely fabric from Boden called Dandelion Heather - it was used for the Florence top a couple of years ago.
However, it is another example of an incorrect depiction of a dandelion (see post below too). Dandelions don't have leaves on the flowering stalks, so technically it's not a dandelion. Sorry to be picky. Maybe the designer wasn't too bothered whether or not it was accurate - which isn't so bad, only this design is just about the least dandelion looking dandelion i've seen.
