I would agree with much of what you had to say I live in Mendocino County
Ca. and there is a bog here people began planting in the 60's. The only
native CP's where D. rotundafolia now there are Darlingtonia, S.
leucophylla, S. rubra, S. flava, a solitary S. minor Okie giant. The
Darlingtonia are polinated and produce seed and spread readily, the
Sarracenia rarely are polinated and so they only spread from the rhizome.
The D. binata & D. dichotoma are in a very small and limited area but the D.
capensis has spread everywhere it is a plant that would have been better off
not planted. This shows that a lot of consideration should be put into what
plants are introduced into an area. If ever you are in the area look me up I
would be glad to show you the area.
Happy Growing
