We had the same warning abut Hogweed here in Halifax, Nova Scotia, and surrounding area. I was eyeballing one - not knowing what it was and having misidentified it as Angelica - and thinking I would gather seeds later this fall. The homeowner had planted it around a city fire hydrant next to a road leading to a public park which was heavily traveled by children. When the warning went out it was all of two days before the plants got smacked and removed by the city.

Thank goodness you were advised of what it was before collecting the seeds.

That's what's worrisome, that some of these noxious weeds resemble familiar plants or look innocuous.

Hi,

I was surprised and frightened to find wild parsnip growing several places in our meadow. Yes, it does look harmless, rather like a cross between dill and queen anne's lace with the leaves of lovage.

Thank goodness we recently went out to New Brunswick where you can still by round up. Funny that agricultural institutions puts out warnings about these sorts of plants but then allows Round Up, etc. to be taken off the market. I think this less evil of the two plant alone is proof that we need this sort of weed killer available to an educated public.
