Mine is in bloom as well with many shoots this year. I am glad you posted yours as I had not be able to completely identify it - I was looking for var. alba and the pictures I could find that most match mine were just listed as L. rubenscens.
I see that a few var. of these are fragrant but not this one - or I am not catching it at the right time of the day. Should it have a scent?
I wonder if daytime temp has anything to do with how long the blooms last as I get about 4-5 days out of mine but we have been hovering around 80F during the day - and lower 60s at night.
