I have often said before that I prefer single flowers to doubles (though I am getting converted when it comes to double hepaticas!) but I must say that this is a striking flower form. As Anne says," it still has a stigma at least. It's nice the way the petaloid stamens stand up in the middle with the true petals reflexed."
It has good foliage, too.
The colour is striking and I would think that this flower has a great future, especially in the cut-flower market.
