Chuck & Christina of Marin County shares with us an aerial albino growing from a redwood on their property. The mutation is quite small and appears to be only 3-4 years old. Interestingly there are a few chimeric branches laced within the mutation which points to more complex genetics than first thought. Another curious oddity is this albino has been exposed to ground pollution (sewage & waste oil) which again might be pointing to a possible man-made cause of this mutation. Over the years we’ll be watching this one for further changes. Again, thanks Chuck and Christina for reporting this albino redwood.
Dennis from Erwitte Germany has sent us these pictures of a four-year-old Coast Redwood seedling that he propagated. Amazingly this year it has started developing sectorial chimerism and is the only case outside the United States that we’re aware of. According to Dennis, the seedling germinated out of a group of two hundred seeds collected from the Sequoiafarm Arboretum located in KaldenKirchen Germany. The arboretum is known for containing impressive stands of coast redwoods & holds a collection some consider home to the most cold-tolerant strains in the world. At a latitude equal with Calgary Canada, winter temperatures frequently fall below freezing. It is not uncommon for temperatures to dip down to 5 F°/-15 C° pushing the cold-tolerant limits with the species. Dennis is currently working on a breeding project with Coast Redwoods to find and develop the coldest tolerant strains available. Due to these weather extremes, it’s speculated that Dennis’s sectorial chimera may have been a result of cold-induced mutation during cell division.
