I posted on your Plant ID forum thread; here is my reply. http://forums2.gardenweb.com/forums/load/namegal/msg0121502231960.html?15 That's probably Red Mulberry (Morus rubra) given the very limited information provided. wgreenlee1 could assist by saying WHERE these plants are growing. From your post here on Trees, I'm going to surmise Missouri - where Red Mulberry would be perfectly at home. I am pretty sure that there are no Tilia sp. with this kind of bark characteristics. It doesn't fit any of the birches either. Not even close on poplar or cottonwood (Populus sp.). Since these plants have been observed by you over a long period of time, I'm certain you would have observed Tilia flowers in passing. You should have seen Mulberry flowers, too - whether male or female. This tree is plenty old to have flowered. Those leaves look large enough, within the range of morphology, and appear coarse enough (along with the written description) to fit right in with Red Mulberry. Lobed leaves are just one expression of Mulberry species leaves, but not the only expression. Your location is significant in answering your question, and additional images of the dormant features like buds, stems, and - be still my heart - the WHOLE tree, make a huge difference in offering lucid opinions to the identity of this tree. Here's an old Red Mulberry trunk for comparison.

if you use stump killer ... properly applied to the cambian layer immediately after cutting flush to the ground ....things will not pop up everywhere .. and you would avoid having to dig this out ... and this would be a good place to do such.. as nothing should be planted that close to the house ... no matter the plant ... and you would avoid utilities.. if any ... dig safe ken

Well... of course, as soon as I post this I find a list from the Arbor Day order (or at least, I think it was that year's order). No idea which is which (which of the ones that came in this bundle actually survived), but could the third photo be a young Sargeant Crabapple? That's on the list, as is Eastern Redbud, Washington Hawthorn, dogwood (I know it's not that), Goldenraintree and crapemyrtle (I remember wondering why on earth they were shipping crapemyrtles to New England!!) In theory (meaning assuming they sent what they said they were sending), it should be one of those -- and the crabapple seems like the only one it could be? I'd be floored if they were shipping free Bradford pears (which is what someone on Name that Plant thought it was as well) -- aren't they considered more or less invasive plants in a lot of areas these days? So I'm hoping for Sargeant crabapple since I wouldn't mind having one of those for the birds (means the little guy can stay right where he is now, in the bird/butterfly garden).

Looks like a peach to me - and to many people on Fruits and Orchards where this question was also posted.
