Hi Michael, yes, they repeat very well. I only kept repeat flowering seedlings out of this cross. Most are quite compact. The most vigorous of the lot is maybe 5' wide and 2' tall. It looks as though they are going to be very fertile.

In my opinion, 'La Marne' hasn't been utilized nearly enough. It has a lot to offer hybridizers. That said, it doesn't self clean which I consider a demerit.
