Daughter says I gave her tese seeds...
Sure I did not ....

A pot of soil....last year
This year 4 seasons later..these " sticks " with a few leaves clinging ( it is fall here in PA ). She bought the soil in this state...I did not send her with anything but seeds..coneflower, blue star amsonia, and rudbeckia maxima. These look like birch to me...what do you think? Thanking you ahead of time

They do look like Birch. Maybe the seeds blew into her pots from a neighboring tree.

I did not think of that

It looks more poplar-like to me. Compare Balm-of-Gilead

I don't know much about the nuances of identification...Our leaves have serration all the way to the tips.. the poplar photo shows the leaf going smooth about 3/4 down towards the tip.... is that enough to make a difference? I think the kids will plant either way..but may make a difference as to location. These are 2.5-3 feet high..from a bare pot this spring it just had amsonia the seeds....maybe that would help identify ..that is a big spurt and the wood is not soft it looks pretty sturdy for such a fast growth.

If you look at the link, you will see that it is only the lower leaf that is not serrated at the end section (not the foreground leaf), demonstrating the variation that can occur even on the same plant. A close up of the twig stem can easily differentiate birch from popular. Birches can be any shade of brown with with thousands of slightly raised white spots, specks, or tiny horizontal dashes. Popular twigs will be shades of gray or green/brown, generally smooth, with sparse raised spots. Birch twigs are quite pliable compared to poplar.

That is a big help !

Supposed to be heavy rain tomorrow but if I get a chance I will go take a peek

Thanks to you both!
