Yes, James, I agree, the bloom cycle is late. I grew Lady Margaret last year, in my zone 4b garden and of the dozen different passi vines I grew she was the first to bloom, starting in July and continuous through the first few hard frosts.
I love passiflora, but did not grow them this year. I tried dahlias on my 100' trellis instead.
I can't find a picture of Lady Margaret, but here are two other pictures from last year.
