As you can see, it is quite different from semiteretifolia - this plant sends out multiple inflorescences, and the flowers develop in twos-and-threes, over quite a long time. Not as impressive as a long foxtail of flowers, but it does bloom off and on for awhile.
I'll try to get a photo of some 'fresher' flowers; I believe each only lasts one day, but appear for several months.
