We love our milkweeds at Spadefoot. Arizona milkweed (Ascpepias angustifolia) is found in Mexico but only gets into the US in Arizona, usually in canyons, arroyos, along streambeds, and hilly slopes at about 4-5000' elevation. Like all milkweeds, it is an important species supporting the beloved monarch butterfly (of which this species is a larval host). 

Plants grow to about 2 feet tall and wide, are evergreen in our climate, tolerating temperatures down to about 15-20º F. Moderate water is preferred, though if in full sun, more may be needed. Plants can tolerate full sun to bright shade, though they flower better with more sunlight. 

Besides being a monarch larval host, this species is a heavy nectar producer, attracting all sorts of butterflies, native bees, and more.
