Courtyard gardens showing off 4/23/2025

Our courtyard gardens between the Race Street Quaker Meetinghouse & our office building are an oasis of peace in Center City Philly. Now showing: Carolina silverbell, lilacs, and a shrub. Could it be alnifolia, aka summersweet or coastal sweet pepperbush?

White blossoms on a Carolina silverbell branch droop from a branch. Out of focus in the background is the Race Street Quaker Meetinghouse.
