Abstract: ‘Grand Mosaic’ is a new and distinct variety of albino coast redwood tree characterized by a non-grafted periclinal chimera exhibiting stable albino growth from inside the apical meristem dome. The new variety contains latent axillary and/or accessory buds forming within the internode of primary branches exhibiting phenotypic color expressions ranging from green, albino, chimera or non-chimeric variegation. Latent axillary and/or accessory buds frequently form in the branch collar zone of primary branches and can produce color expressions ranging from green, albino, chimera or non-chimeric variegation. Further, the branches demonstrate horizontal to drooping-like habit and moderate-to-fast growth depending on the amount of albinism compared to other common green redwoods.
