Sansevieria subspicata
This is from my garden and tonight the flowers all bloomed at the same time. As with many night blooming species, the fragrance was so overpowering (in a bad way!) that we had to take it outdoors.
For more surprises (in a good way), visit our wonderful host, Dragonstar, at http://blackandwhiteweekend.blogspot.com/
Thanks for stopping by!
