- Jacobson (1996, p.18) provides the following on Armstrong: "The original specimen was bought for $5 from a farmer near Hartgrove, OH, by Newton G. Armstrong (d. 1963) of Armstrong Tree Service, Windsor, OH. Mr. Armstrong in 1948 told his friend Ed Scanlon about it. Propagated by Scanlon nursery in 1949, but only offered in quantity by 1955-56".
- Armstrong TwoTM - possibly more dense, tighter form than 'Armstrong', reportedly has better fall color (orange-red), however, some authorities do not see any differences.
