Hooray! Triple score! Thank you, Embothrium!

Do you think I dare transplant them at this stage?

You're going to have to.

I said "of those" because otherwise I wonder if the two are Tanacetum vulgare.

I think you nailed it with the tall marigold because it looks just like what I grew there in prior years. I tried to buy seeds a few weeks ago but everywhere was sold out of marigolds! I had to settle for the 6 inch kind. This is what I wanted.

If left as is, the tomato will engulf the marigolds.
