Another mystery plant

[Roma]

I think this came from birdseed.  The leaves are soft and clammy.  Any ideas?  I am leaving it to flower but it may be too late.  Where it is growing gets very little sun now.

It almost looks like a Nicotiana?

Sweet Rocket?

I'd smoke it before I'd eat it, but no resemblance to the tobacco or rocket I've grown.

Here's a challenge! It's definitely not sweet rocket, as this doesn't have the glandular covering. Matt, I think you may be along the right lines, it has a Solanaceae look to it. I wondered about a Hyoscyamus (though not sure henbane is the best idea in birdseed)?

Guizotia abyssinica, from niger seed?

[Maggi Young]

I think Matt's got that right - we had it once from birdseed and decided that was the ID when it flowered.

Thanks, Matt and Maggi.  It did remind me of Nicotiana but the serrated edge to the leaf did not fit.  It is mixed seed I use so did not know if niger was present.  Hope it manages to flower.  I had a fair idea of the identity of the other plant I left I left to grow.  It is now confirmed as oats.
