Little white flowers that often pass unnoticed at the edge of the woods, where they can be surprisingly abundant. Like many members of the rose family, these plants are a bit sloppy with their petals, which sometimes look rumpled as though they’ve been slept in. These plants were blooming in Bird Park, Mount Lebanon.

A little mallow that grows in lawns and vacant lots everywhere. It usually passes unnoticed as just another weed in the grass, but a close look at its flowers shows us that they are just like Hibiscus or Rose-of-Sharon flowers, but on a smaller scale.

This popular garden flower often escapes, and where a patch has once been planted, it reseeds itself year after year, spreading to wherever the seeds are carried by rain and gravity. It’s known by a large number of common names, among them Persian Jewels and Rattlebox. The latter name refers to the seed pods, which grow to balls about an inch in diameter that rattle when the seeds ripen and dry. These plants were growing on a bank in Beechview.
