| Description | As the common name would suggest this showy annual comes up after summer rains, forming carpets of yellow/orange blooms. Summer poppy occurs in central and southern Arizona, from the desert up into the grasslands. This species fills a niche occupied by gold poppy in the springtime. Though they bear little external resemblance to one another, summer poppy is one of the few native plants in the same family as creosote (Larrea tridentata). |
