On our trip, Forbes and I had the pleasure of visiting four Darlingtonia sites in California and Oregon. The four bogs represented three different habitats, all of course with a water supply and serpentine soil/rock. Here are some pictures:
Darlingtonia Wayside, coastal Oregon
There wasn't much to see here, other the sad sight of surrounding vegetation relentlessly encroaching on darlingtonia habitat. The Darlingtonia themselves were probably the tallest we saw, but rather color-less.
A large open field in the same area:
This field had in the past been used as a Darlingtonia harvesting ground to supply retailers such as Safeway. Luckily some of the plants survived this raping and a good sized population now seems to be flourishing. Almost the entire bog is composed of mounds of sphagnum, and D. rotundifolia is also present.
