Black locust trees (Robinia pseudoacacia) are an invasive species in Massachusetts, but it is difficult to dislike them this time of year, when the trees perfume the air with a jasmine-like scent. The trees can no longer be legally planted. Older trees can be found in yards, but most of these trees grow in minimally-maintained spaces.
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
