Spring has arrived early this year. The lilacs are in bloom. And most of the trees at the Arnold Arboretum have either bloomed or started to leaf out.
A few species still wait cautiously. Among those that have yet to wake:
- Ailanthus altissima — Tree of Heaven
- Albizia julibrissin — Silktree/Mimosa
- Catalpa ovata — Chinese Catalpa
- Fraxinus excelsior — European Ash
- Gymnocladus dioica — Kentucky Coffeetree
- Rhus chinensis — Chinese Sumac
- Robinia pseudoacacia — Black Locust
