Yes. The photo shows "some" Drosera capensis. There were many more.
I can understand someone wanting to enhance an easily accessed Darlingtonia site. In fact that part of the site was "enhanced" by CalTrans when 199 was widened. Never mind the bulk of the fen was destroyed. But planting Drosera capensis in a site with a very nice population of Drosera rotundifolia?
Hmph. This is a new comment on a very old thread, and is a matter of preaching to the converted, but these kinds of plantings encourage the notion that Drosera anglica is wider spread in California than it truly is!
Get rid of D.capensis where you find it. As many will know, it is a notifiable pest here in NZ in regions where it happily grows. Crowds out native D.pygmaea and can quickly become a carpet of unwanted red across suitable habitat. The biggest issue consequential to transplanted or wilding D.capensis is, of course, flowering and seed dispersal. Hopefully most of the plants in the location above have been removed prior to that occurring or it will become a weed indeed. And then again, missing a bit of the root stock when removing amounts to asexual propagation.....
A lot of people remain fascinated by seeing any CP in the field and like to leave things alone believing everything is part of the Gods' Garden. Good news that people like John are knowledgeable and do the removal job on this pesky species.
People shouldn't be planting carnivorous plants where other carnivorous plants already are. At the very least, they should try planting them where there haven't been any before. Otherwise, it's just CP versus CP.
Hypothetically, a CP enthusiast who may cultivate something such as D.capensis could unwittingly carry fine seed attached to their clothing, on their shoes etc thus delivering them from home to a visited wild habitat. Invasive water weeds are spread in this manner. Any-which-way, once the species is up and growing it will likely be a real pain in the butt to get rid of as it will spread itself.
John, did you conduct follow-up visits to the site in question to see if the presence of the invader continues?
I'll check it out next time a trip is made up there, we found some dinky Cannabis plants there about a decade and a half ago (growing uphill in the thicker shade). This site also had a few Sarracenia hybrids last I saw it, but not sure if those have been pulled out. While I love the neat variants of D. capensis, there isn't a single plant in the collection these days for this very reason.
