Trailing Four O'clock (Allionia incarnata)
The low-sprawling plant shown on the banner image above was flowering along the Pool Wash Ridge Road in April of 2004. These plants may sprawl to a distance of 10 feet, and may bloom throughout the southern Arizona warm season from March to October.
The leaves are "dirty green above, slivery beneath; sticky, hairy, oval; to 2" long (Epple, cited on main Wildflowers page, p. 58), and they also have "wavy edges" (Niehaus et al, p. 306). This is a perennial herb, with sticky stems, and it grows in a wide variety of places on our lands.
see the image at right, taken in the West Wash of lower Hot Springs Canyon in August of 2004. (Click on the image for a close-up of one flower). Members of the Four O'clock Family (Nyctaginaceae) have flowers which, despite their appearance to non-experts, lack true petals. Trailing Four O'clock is also known as "Trailing Windmills", by virtue of the similarity of the flower to a windmill shape. The flowers often occur in threes
Note the hairy leaves of this plant, which appear clearly in the close-up. (Note also the greenish bug enjoying the flower.)
