I misidentified this flower last week. It's not a coreopsis; it's a cosmos. Same tribe, different genus. But do I get partial credit since they're fellow tribesmen?
We were all excited that one of our California poppy plants was about to blossom, worried constantly that they'd be eaten by deer every night, and then cosmos popped out instead. Here's to beautiful impostors. Or to garden ignorance. Hell, here's to the weekend!
