Lori, there probably were flowers but it had been clipped into the formal shape so any open ones had gone. There were some bluish looking "threads" where one might have expected past flowers and I wonder if those were the remains of spent blooms, corolla detached. I'd tried to photograph those but they didn't come out clearly.
Greene, thanks yes, I emailed the gardens yesterday (actually a historical village) so I hope I get an answer.
