Identifying a Mystery Tree in Northern Illinois

A tree with ash-like leaves but clusters of greenish-yellow, fuzzy berries has stumped a homeowner in the Chicago suburbs. Without photos or more detail (bark, habit, flower), definitive ID isn't possible remotely.

Best Next Steps

1. Contact the Chicago Botanic Garden – their horticulturists can ID from description or photos. Website.
2. University of Illinois Extension – local master gardeners often assist with ID.
3. Arborist consultation – a certified arborist can visit and identify on-site.

Key features to note: leaf arrangement (opposite/alternate), bark texture, flower/fruit structure, tree size and form. A clear photo of leaves, fruit, bark, and overall shape dramatically improves accuracy.
