garberia, Garberia heterophylla

Garberia only grows in Florida, where it is threatened. On first impression it doesn't look much like a member of the aster family. It's a bush a couple meters tall. The flowers look like clusters of something - well, not aster like. But if you think of the boneset/thoroughwort tribe, you can start to see the connection. Are the flowers white, becoming pink? Or pink fading to white? Judging by the less mature pistils of the pinks, pink comes first. Garberia grows mostly in Florida's scrublands. Polk Co FL, 10/21/15. Aster family, Asteraceae.
