kill it now .. do NOT let it go to seed ... free.. mystery plants.. are usually the ones.. that are horrible weeds that seed prolifically ... and the bargain part of the equation rarely works out .... ken

I filled them with jiffy organic seed starting mix (peat, vermiculite, coir, lime) with some extra perlite added to it. I know exactly where the seeds came from because I personally opened the brand new seed packet and poured them out into my hand. I even marked the side of the peat pots with an arrow and the words "diff seed", right where they were located in the pot. And those are what came up. I would sure hope to God that is not water hemlock!! It never even crossed my mind that that's what it is, that Burpees could make such a mistake! But looking at it now, I think you are correct. And it wasn't just one pot with it! There were several of those seeds and I planted each one so I actually have several of these water hemlock looking plants growing in my garden. I am definitely contacting Burpees!

This is great news floral! I've never grown Bupleurum before. As to how it got there, I'm not sure. I've scattered many, many kinds of seeds through the years and maybe Bupleurum was one of them, but I don't remember. Thanks everyone, can't wait for it to bloom!

The third picture is wineberry, an invasive Asian relative of the raspberry. Birds spread the seed and I hear they are growing all over the east coast now. We first saw them in Ohio and purchased some for our garden. It is against the law to sell them in several states, but not in Indiana. The fruit looks more like a black raspberry, although in a bright red color. They are delicious too. You can use them any way you use raspberries. Those husks will eventually open to reveal the fruit underneath.
