This spring I'm planning a big bed of zinnias. I'd like to do some cross-pollinating as per Zen_Man but as a test I'd like to find a (reliably) tall, (reliably) single-colored white strain of Zinnia elegans (AKA Zinnia violacea).
There are several listed out there but I know some of them have poor fidelity (i.e. some have many short plants and some have cream- or yellow-colored flowers).
So I ask for others' experiences: are there any large, white, varieties I should look into?
Short of that, what is the largest, darkest, purple variety that's readily available?
Thank you, thank you and Merry Christmas!
