I've been exploring plant identification with a focus on native species. Now that I'm starting to see flowering plants coming up on my property I'm trying to identify some of them. I'm in Eastern Douglas County, Colorado. I think I'm starting with a pretty hard one, but not much else is in bloom yet ... so here goes. Pictures attached.
Given the compound umbel I'm thinking it's in the parsley family, which could make it really toxic. Valerian also seemed like a possibility. I see five white petals with some purple, no easily identifiable sepals, no visible pistils, and what appears to be between 1 and 3 purple stamens. The leaves appear to be in a basal and opposite configuration. The stem and leaves both appear fuzzy, and the stem is purpleish.
I don't have any intention of eating this plant, being so inexperienced at this ... but it does grow in my dog run, so that concerns me a bit. Anyone have any ideas?
