Growing notes
- Vivid uniform scarlet autumn colour late October — among the most reliable autumn-colour maples
- Distinct from the base japanese-maple entry — selected cultivar with consistent colour rather than variable seedling stock
- Larger growing than most palmatum cultivars — eventually 6 m tall and wide
- Prefers dappled shade or morning sun and shelter from drying winds
