Thanks for the update, I have some integrifolias, Baby Blue for example, which only reach about 1 ft tall when mature. Possibly some of your smaller seedlings could be dwarf forms.
Others such as Alionushka, Blue Rain can reach 8 ft , lovely at present in a tripod of long hazel twigs.
All are reliably hardy and will be happy in a cold frame over Winter, I usually pot mine on into larger pots in Spring.
The picture is Blue Rain taken yesterday.
Good luck with the seedlings, a tall white form would be nice, please.
