Apparently

a sneaky squirrel deposited an acorn into my geranium window boxes and this little oak tree popped up. I couldn't beat to just toss it, so I put it in its own temporary pot while I find a place for it. Mind you, I live in an apartment, so that may be difficult. I think, judging by the other oaks around here, that it's a pin oak.

One quick note

Anne Frank: Saplings from Anne Frank's tree take root in D.C., US

Eleven saplings grown from seeds taken from the chestnut tree that stood outside the Amsterdam home in which Frank and her family hid are being distributed to museums, schools, parks and Holocaust remembrance centers through a project led by The Anne Frank Center USA.

The first sapling will be planted in April at the Children's Museum of Indianapolis. Other saplings are being sent to a New York City park honoring 9-11 victims, a Little Rock, Ark., school that was the center of a desegregation battle and sites in Massachusetts, California, Idaho, Michigan and Washington, D.C.

The chestnut tree itself, which has suffered greatly from a fungal disease, was due to be chopped down, but has been granted a reprieve for now. But even if it is lost, its legacy may live on in these various places where the saplings are planted, I think Anne would have approved.
