Like many of the fancy leaf Vrieseas, the flower on this Vriesea "Forrest x Milky Way" lasts less than a day. This flower came out this morning and by mid afternoon it had gone.
The flowers are carried on a disproportionately long flower spike that lasts for many months. See http://365project.org/organise/media/5407515
These hybrids are fertilised by hand so you can imagine what a job it is.
Best on black
@hermann Yes Sally. If you look at the other pic, you can see the remains of the flowers that have opened earlier. They seem to open progressively from the bottom up. They will last for ages on the flower spike
