My Montmartre isn't a fast grower either, but has bloomed every year. I love Moonlit Water so think of me next year Tom!
All my other luminatas are new this year. Telepathy started slow, but seems to be growing pretty well now. Pep Rally, Clarence and Delirium are small, but have new growth. Quench came as a pretty big rhizome, but too soon to tell. And Silent Wings is doing really well.
I plan to pick up Vapor and Elizabethan Age next year. Assuming I get another bed built.... (like that is not going to happen!)
