A photo of a group of the usual Pinguicula agnata. The flower color varies, mostly due to the age of the individual flowers. As you can see, this species often grows to be a partial clumper, though not quite as prolific at producing groups of crowns like some of the smaller clumping species. A much higher resolution copy of this image is at:
And, apparently even propagating by leaf-pullings can produce "sports". I have one plant from a group produced by leaf-pullings that produces flowers that appear "double", in that they have double the number of corolla lobes in an apparent side-by-side mirror image double appearance, with two stigma, but only one ovary beneath the corolla. If this turns out to be stable -- that will be a horror for the species purists.
