it reminds me of Alexanders (Smyrnium olusatrum)
I planted alexanders a number of years ago. It has naturalized like gangbusters, to the point where I fear I have introduced a new invasive species.
If only my native umbellifers were as prolific.
Alexanders has a very wierd taste. It's useful for about two weeks a year, when the stalks are tender. The leaves are way too bitter to use. Maybe the seeds would be a decent spice, but I haven't bothered to try.
The anise swallowtail is the main (and most desired) insect I have seen on umbelliferae around here, and I don't see any on alexanders. So even though I eat it every year, I have started to remove it, and continue to try to establish natives like biscut root and yampah, as well as learning to eat native cow parsnip and my local angelica (hendersonii).
