Witch's broom or minature? (2 Replies)

Posted July 10, 2018 at 4:28 pm

So, I’ve got these two little babies here, one Bristlecone and one Limber pine. They were grown from seed and then potted in these #1s. They are both 24-26 months old. I was wondering, based on their current habit, do they look like they’re mutating as a witch’s broom, or are they miniatures? Can these things be known at the 2 year old stage? Does anyone else have experience with mutations this early? The bristlecone has about 20 shoots off that little 2″ stem.

Brandon: Seedlings can’t be witch’s brooms. They can become a cultivar if they are different from any recognized existing cultivar. You need to be patient in evaluating exactly what your plant will become. It often takes five years or more to understand the stability of the plant. In the meantime, document the yearly changes with pictures. If you feel that the plant warrants registration after the 5 year process, contact your regional ACS officers for assistance in the registration process.

Byron: I’m not sure at what age the mutation could begin, but I had a 3 year old P. strobus seedling that had one central leader and a broom off a lateral shoot, about 4 inches wide with over 50 buds compacted in that little ball. Unfortunately I killed it! After spending more time with these two I’ll know better.
I don’t know much about witch’s brooms but based on my experience with the white pine, I wouldn’t rule out a broom on a seedling yet. It is much more likely that these are just interesting finds though.
