We are happy to make suggestions, but more information would be helpful. What mature height (without relying on pruning) would be small enough? "Small" trees can still mature in the 20-30 foot range, at least after a decade or more of growth. There are some dwarf options for some species as well. Is there a roof downspout emptying nearby, or anything else potentially adding extra water to the planting site? Do deer walk though the property, either eating foliage or rubbing antlers on trees in the autumn?

That does help, thank you. Below are some ideas for species to consider (native unless noted), though it's not an exhaustive list, especially since there are numerous cultivars (with traits like a more compact mature size or variations in flower or leaf color) within several of the species listed. They'll support pollinators, birds, and other wildlife. Botanical names are in parentheses. We've skipped over a few more species (like American Hornbeam, Carpinus caroliniana) that should do well with the site conditions but which won't have showy blooms or berries, even though they still support insects and birds. Similarly, we've skipped a couple species that meet the other criteria but which would prefer partial shade rather than full sun (Flowering Dogwood, Cornus florida, and Pawpaw, Asimina triloba).

• Sweetbay Magnolia (Magnolia virginiana)
• Serviceberry / Shadbush / Juneberry (Amelanchier, several species and hybrids)
• Eastern Redbud (Cercis canadensis)
• Crabapple (Malus, several species and many hybrids) -- not technically native, except for a couple species that are hard to find, but not invasive
• Green Hawthorn (Crataegus viridis, commonly available as the cultivar 'Winter King')
• American Fringetree (Chionanthus virginicus)

Several of the above (often magnolia, serviceberry, and fringetree) can be multi-trunked or single-trunked, which is purely an aesthetic choice as it does not impact final mature size or other features.

You're welcome!
