Thanks for the explanation, Bob.
I have Zua, but it isn't blooming yet this year, although it's setting buds.  I need a much better picture of it to send here.  :)

El; A sport is generally considered to be the mutation of a single gene during vegetative growth. That one gene can effect a number of characters but the most common example is a blue Iris producing a white sport or vice versa. The Sport may be fairly stable and continue in the new form for many generations. Example Iris albicans will occasionally have a blue plant appear in a large population of white. The blue form has been registered as Madonna which if my e-mail would allow should be within single quotes. The Botanical rank of Forma is generrally considered to be a single gene difference and can also be named a cultivar. Zua is believed to be a single gene difference and has a crepe like texture to the flower parts. I used to grow it but it has many years since I have seen a plant and eventually would like to find it again. The is also a sport of Zua that is known as Blue Zua, that is blue rather than the lightly blue greyed white of Zua. I can remember I had a slide but it was terribly out of focus.
