Sunrise 6:11 am: What's a clown flower?

"These are cheery," remarked the male Dawn Jogger as the two DJs passed a bushy plant with shocking pink blooms near Roble Field. "They're clown flowers." That got the female DJ to ponder what a clown flower is. Is it that flat flower which squirts water that clowns carry around? Or is it something that reminds the viewer of a clown's face? A quick search revealed that there is actually something called a clown flower, sometimes planted as part of a hummingbird garden.
