It's funny/perfect you would bring that up! I'm actually growing Sugar Magnolia Tendril and have two Parsley Pea rogues/sports in the ground. They haven't flowered yet so I don't know what pod color I'll end up with, or even flowers for that matter. But one of the Sugar Magnolia flowered for the first time yesterday and yes, it looks nearly identical to your picture, and also nearly identical to what the once Red&White Cascadia has now morphed into. I'm writing up another post with pictures to post in a couple hours -- I just need to duck out to the garden and get one more picture and upload it before I do.
That's really become the main question. With each passing day, the blossom gets more and more 'purple.' I'll have pictures to show later today. But unlike normal purple flowered peas, it seems to start out without that pigment, and then develop it over time, perhaps due to my sunlight theory or some other cause. So, while still curious, the mystery as to what genes are acting on it seems at least partially solved, thanks to you.
As for how it got into Cascadia, am I right to assume that this must be an accidental cross? Learning what I have so far from you all, the white flowers of Cascadia are recessive, so apart from an extremely rare random mutation, it's most likely that something crossed this pea at the seed farm with a variety that carries pigment in the flowers. The plant is exhibiting bush characteristics, so since tall is dominant (if I remember what little I recall from Mendel) then the cross was with a bush variety with colored flowers. Just spit balling here, but I'm always curious to know the possible parents of unexpected crosses, in the hopes that it will make understanding and predicting the F2/F3 etc easier.
