Maurice,
Sorry, I can't say that I noticed any difference in the color of the blooms. If there was it must have not have been very distinct, but then I get so busy during bloom season I could have missed it..... Now you have me curious, I will make a note to check for you this summer.
Did a little bit of searching for those who might be interested and found two more...
Malja, a diploid with yellow blooms is trademarked and sold as Golden Zebra
Variegated Jackpot, a tet with melon bloom
Very cool corkscrew foliage!
