Flower power

It's Spiderling season! In addition to Scarlet (aka Red) Spiderling (Boerhavia coccinea) above, Bush Spiderling (Commicarpus scandens) and Erect Spiderling (Boerhavia erecta) are blooming in Sabino Canyon. These plants tend to sprawl and branch and have tiny flowers. All are in the Four O'Clock Family (Nyctaginaceae).

Coulter Hibiscus (Hibiscus coulteri) is in the Mallow family (Malvaceae). Unlike the photo above, these plants often grow vine like on and among other plants.

You won't see Arizona Poppies (Kallstroemia grandiflora) in Sabino Canyon, but you've probably seen them along roads in Tucson this summer. They aren't really poppies (and thus are unrelated to the Mexican Gold Poppies that bloom in the spring). They're in the same family as Creosote Bush (Larrea divaricata var. tridentata), namely the Caltrop family (Zygophyllaceae).
