I'm disappointed!
Before Google intoduced the "images" search you just had to click blindly through the results list.
For some time now you can enter a plant name, search on "Images" and for any particular plant, you get any colour under the rainbow - very often (supposedly) for the same cultivar.
Now I can excuse difference in shades.
Before I found better settings, Ive taken a photo of a mauve/pink Erigeron with my digital camera only to find it BLUE on my computer.
But, when you know a cultivar should be Pink, and you find the Image results showing WHITE plants, theres something wrong!
