Description It's not uncommon, that strolling the Sonoran Desert near towns like Phoenix or Tucson, you will come across a strange primeval looking artifact that resembles the recurved claws of some long extinct beast. These strange looking hooks are the dried seedpod of devil's claw, a summer annual with hairy, heart shaped leaves, tubular pink flowers, and the strange pod which ends up laying on the desert floor waiting to snag passers by. Proboscidea parviflora prefers well draining, sandy soils, but with a little moisture and humidity it can tolerate many different sites and soil conditions. In habitat these plants tend to be no more than a couple of feet tall but can get relatively large with supplemental irrigation. The blooms make this a worth while plant to cultivate, and the seed pods make it one of the most unusual wildflowers of the Sonoran Desert.
