I has me thinking of the way that the horticulture industry went with coloured plants, I once saw a Blue rose.
I wonder if this is cross breading or man is involved with synthetic hybreading.
For the majority they have jumped up tremendously. I remember mine I paid 65 (and thought I was crazy) for 3 years ago that had alot more color that that, but one almost the same sold recently for a few hundred. No auction. Just dealer price.
