Growing notes
- Reliable autumn colour late October to mid November — fixed display rather than the variable show of seed-grown trees
- Selected for fertile cool climates (e.g. southern UK) where the species can struggle to colour reliably
- Sets fewer of the spiny seed “gumballs” than seed-grown stock
- Slow growing — eventual size still substantial, allow space
