Hmm....rather confused naming of the seed there, Howard! Nomocharis mairei is not the same as Nomocharis finlayorum ....the latter being a name given to a race of hybrids thought originally to have arisen in the garden of the Knox-Finlays, in Scotland. This hybrid is a mix of varioud types, giving a stable enough plant which is robust and lovely.
Your babies are still a bit little, thought it may well be that next year they are big enough to make a wee flower...I would pot them on, en masse, and give them another year of pot growth before you put them out to endure the rigours of the garden in Nova Scotia.........better safe than sorry, etc!
