We didn't get quite enough autumn rain to wake up many varieties of desert flowers.
So, the botany department at the Arizona-Sonora Desert Museum tells me that the bloom will be "so-so" this year. They say the "hills and flats will be very green, but much of it may be Popcorn Flowers and Filarees." These aren't quite as beautiful on display as are poppies.
The botany department frequently updates their wildflower hotline. Just call 520.883.1380.
