Looking at the children's stats, I have a feeling that Big Snowbird is a dormant. For postage though, it's worth trying to use for hybridizing however long it lasts in my garden. Some dormants do not survive for more than 3 years in warm Florida. All I need is a season or two of blooms to use as a parent crossed with some other rust resistant sev or ev cultivars or seedlings. Maybe I can clean up the color on my Stippled Statement x Alexa Kathryn seedling by crossing it with Big Snowbird? Worth a try!
And boy! do I love the look of "Remembering Ruth" which is a cross of Big Snowbird x Beautiful Edgings. NICE!!!
