Can’t think of N/A equivalent spino - hardy hybrid for bloom size and color except maybe my yellows and white spino / altaica.
Waiting for my “maybe” or “not” but very hardy, robust pinked altaica (labelled as) to acclimatize to new ground and environment single bloom on sucker was small - btw way have a hard time believing altaica / spino - if so not likely a strong background (due to leaf form color and canes - conjecture but seeing is believing more in label).
As a part of long term program planning, wondering if any Northern European or other locales workers have tried hybridizing with it?
Large bloom size, single, c/w mild pinking and hardy, are main potentials for me.
