The butterfly in that image is an orange sulfur, Colias eurytheme; I found it dead on the sidewalk at an interstate rest stop. I was in such good condition I collected it.
Another plant has bloomed in white - but it's not the promised 'Ambroise Verschaffelt'. And another has bloomed with bluish flowers which are very handsome - but again the name does not match the flower.
A group of Sinningia speciosa has produced the same result: handsome, lusty growers and beautiful in bloom, but not a one true to name.
