Spotted this improbably beautiful flower one morning on my walk to the train, growing in a gap between the brick walkway and a lightpost. But it only has 1 flower at a time, & they only last the morning. So I stalked it for weeks, watching to see if it had buds that looked about to bloom, and toting my camera & trying to leave early for the train if it did.
I love the seed capsule, too -- that's a developing one next to the flower, & a couple of mature ones out of focus below.
