Thanks William! I guess I thought that the seed producer had already created a strain that was consistently pink but I guess not.
I'm not sure how I would tell which plants would bloom pink or blue. They all appear identical to me with purple buds. Plus they all seem to open their flowers in the very early morning. I check them before I go to work and the flowers have already opened.
Instead of spreading the seed this year I may collect it and start plants indoors next year. This way I can wait until they bloom before deciding which to plant outside. I can also pollinate a few myself and collect those seeds specifically. Thanks for the advice!
