T. recurvata does bloom, but they are fairly inconspicuous. I thought I took photos last year when one bloomed, but I can't find any. Closeups are hard for me get successfully. I know I tried, but I may have deleted them as useless. I have one where you can clearly see the seed pods, but not a bloom. They are small, pale sort of grayish purple blue and so the contrast isn't great between the bloom and the foliage. You have to have your nose right at it to see them - and you have to be looking or I think you still might not notice them.
