I may have to repost this when in bloom. It's going to shade my very sluggish New Jersey Tea, so I'll have to move it. First time my Camassia scilloides boomed. Weed are coming out, slowly, but surely. Pulling Erigeron to make way for the Portulaca! :)

I wondered if it could be a Bupleurum but did not post that thought earlier.

Thanks for the ideas. The leaves are waxy. Do all Bupleurum lack petiols? I will post again when it blooms.

I noticed the perfoliate leaves. That would fit Bupleurum..

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!

I'm not saying it is definitively Bupleurum. Just that the perfoliate leaves fit.

I know floral. Just think it would be cool if that is what it is. Whatever it turns out to be is fine with me, I have so many species already and now have 2 gardens to manage. I relish your wisdom and your words. :)
