I have just moved my Gertrude, Yvie, so glad to see your's is doing well. Mine was planted too close to a lilac years ago, which is what I do when I get excited!
Agapanthus experts seem to differ over whether crowding is good or not. My oldest and most congested pots are beginning to lose their flower power, and if they don't do as well this year I may hack them out and start again. I may need and axe.
I will always grow them in pots though. I bring the evergreen ones inside in winter and cover the deciduous types to keep dryish.
