Well, I stopped for flowers of some sort, but they weren't exactly roses. I didn't mind: They were flowers I'd never seen before.
I've seen other plants with buds that were bigger than those flowers. Still, I assure you that they are indeed flowers, petals and all.
My cell phone camera didn't quite capture what I saw: a kind of pointillist scrim of purple in the garden of St. Luke in the Fields. I have no idea of what they're called, but whatever their name, they made me happier today.
