I don't know what buckweed is but that looks like a tree seedling or sucker to me. Possibly a crabapple? Are the purple leaves below it part of the same thing? And what are the reddish naked twigs to the right?

Pyrus, probably a seedling Callery-type pear. I tear out many all the time. I have a grove of them to do yet. Weeds from a weed tree.

Callery pear was my first thought as well.

Thanks, Callery Pear makes sense. The previous owner had one planted near the front yard, and as much as I don't like it, it does nothing bad and flowers nicely and has nice color. Just the other day I watching a squirrel 20-25' feet up reaching for the little fruits.

and as much as I don't like it, it does nothing bad

==>> what???

using the word DESCRIPTIVELY .. its invasive ... as.. by definition.. it has come from another plant on the property.. if not from a root sucker ...

whats the upside under that DESCRIPTION???? .. only that it was free???

get rid of it ...

The smell of the flowers may help change your mind.

Hmmm, my only question was to identify the seedling.

The seedling will be removed, no interest in keeping it. The larger tree, which is about 70' away and about 25' tall, very columnar, and about 8" caliper, will stay for the reasons I mentioned. I have never noticed any problems with the smell of the flowers, but they are above me and hard to reach.

Thanks,

Pears are remarkably pungent in flower, close proximity not necessary.
