Found them!
There are not many sites for
Sarracenia flava in Virginia, and I was told by my sources that this
site was probably the best. The site was along a powerline right-of-way.
Such areas are often the best (or only) habitat that remains suitable for
carnivorous plants--human development and changes in the land use have
screwed up the habitat for carnivorous plants elsewhere.
These all-green plants are
Sarracenia flava var. maxima.
Also at this location, by the way, was
Drosera brevifolia, Utricularia subulata, and I think I
recall seeing Drosera capillaris.
Frankly, while it was nice to see the plants,
there were not very many. In Florida, a site like this would barely merit
a GPS check and entry in your travel journals. Virginia just does not have
many of these plants left!
(Incidentally, before you e-mail me asking about this
location, I will warn you ahead of time that I cannot reveal the location
of this site. Sorry.)
