First of all, can you tell us where these seeds came from (country, state)? Can you describe at all the plant (what the leaves looked like or the flowers)? The pictures are too small and they are not clickable. If I right click on them, I can grab the url and paste it and then view it - very tedious. If I try to just view the album, it says it is private (George W Bush?). Can you just give access to the album to make viewing the pictures easier? Here is the first picture:

Simon & Quirky- Thanks oyu both for your responses. The two examples that you've identified as red maples make sense. As far as IDing the Norway and Sugar maples is concerned- when you describe the Norway sap as "milky" does it actually appear to be white (like milk or glue?) or is it just cloudy? I was trying to look at the sap yesterday but it wasn't obviously cloudy on what I expected to be the Norway. If I wait until the trees produce seeds I suppose it will be a bit easier to tell which is which. Thanks again! -Josh-

I never looked at the flowers on mine that closely, but from the description it sure sounds like Creeping Charlie to me! Goes by lots of other common names too, so when doing research make sure to use the Latin name, Glechoma hederacea. Good thing you don't want to get rid of it, because it ain't easy!!

For #2, compare to H. glabrata concolor - here is mine; darker than yours but looks similar otherwise (shape of leaves, pupping): H. pumila (left pic) seems to have 'fatter' leaves. And there is Haworthiopsis attenuata var. radula that is somehow similar too (right pic):
