While poison hemlock gets very little mention on the recently revised official Elkhorn Slough site, in my humble opinion, it is the single most dominating weedy species on their coastal, publicly-accessed grasslands. There are massive stands of it, not only in the expansive area it encompasses but also in height. Andy was kind enough to provide a size comparison for me to show it readily grows to 8 feet tall at Elkhorn.
Per my m.o. for Nature ID, all these photos were taken on November 12, 2011. This means the typical blurb repeated everywhere from books to online that C. maculatum flowers from April to July is not entirely correct. It's obviously flowering here in November, so it's no wonder it's such a productive plant. The flowers and leaves remind me very much of Queen Anne's lace and garden carrots.
I was sorry to see Land Steward ceased blogging about Elkhorn Slough. In fact, I discovered several blogs that featured Elkhorn Slough have stopped abruptly in the past two years, which makes me wonder if all the staff and volunteers were asked to stop blogging about their experiences. I now receive weekly, glossy, sugar-coated e-mail updates on what is going on there. It's too bad; I preferred the nitty-gritty and personal perspective of the reality of land management.
Did you notice the other unwanted resident in the first photo, a cucumber beetle?
Oop, I guess I should also note that there are other hemlocks out there besides the ones in the Apiaceae, aka carrot family, such as those in the pine family like Tsuga spp.
