Pea flowers above the quarry |
Visitors to Halibut Point last week encountered a spectacular view of the Babson Farm Quarry, framed in pea flowers.
The white blossoms, distinctly pea-like and with crimson centers, hung in racemes from black locust trees. Fortunately some were displayed at eye level for close appreciation.

themselves but the succession of plants that coexist with or follow them.

The brief flowering of locust trees is an
event worth marking on June's calendar. Then the fallen blossoms carpet Park
paths like the aftermath of a tickertape parade.
