Thanks, everyone!
Elena, I noticed this one starting to spike in early November, so its taken just over two months. I am not sure how long the flowers are supposed to last, but I think I am going to cut the spike on this one (since it is still a single growth plant). I really want the plant putting energy into growth.
The petals on this one don't appear to be as wide as some of the other ones posted here, but yes, as Fren says, it is very symmetrical. I think that the darker veining coming together at the center really makes the white staminode stand out more than on those plants with plain green petals.
Rick, as I grow my plants quite cool in the winter, I am careful to keep them on the dry side. But thanks for the warning. I will watch carefully!
Thanks for looking!
