Hi Nicole, Glad you made it too ATP! Lynn, somewhere the handout from spring 2013's clinic got posted and it has a list of common traits that are dominant - like "reds and purples" (which surprisingly to me, are dominant)
Several of us have noticed that we're getting many blooming this spring/early summer, and I myself have moved my bloomers all in one section of my yard so they can randomly pollinate! I have some fuzzy ones, some webby, large, small - a huge mix and I'm just going to see what happens!! I notied today that there were lots of bees all over my semp blooms!
(Nicole, there is SOOO much info on here, and only some of it will be directly pertinent to what you're looking for, but we are a fun group, so make yourself at home!) Oh yeah and these folks LOVE to see photos, so maybe you and your son can make that part of your project, photos of your noids!
(just a suggestion!)
Cheers
