I agree about part shade for a darker Purple Prince lily. Same goes for any dark petaled bloom.
Brecks has such a bad record I just automatically look somewhere else. When the coments are running in negative numbers larger than the positive ones Its a clear indication to choose another vendor.
As far as shopped images goes all vendors are at fault. Many buy images for their web pages from a image service,thats how you see the same plant on different websites The website isnt at fault only in that they allow a image to represent their product. When I am looking for a particular plant I check Plant Files or database to see if gardeners have posted pix from their gardens,that is the best indication for size and color in my book.
