Matthiola parviflora is a Mediterranean annual in the Mustard Family (Brassicaceae) that has recently been documented for Tucson, Arizona. To determine the U.S. distribution of this exotic new arrival, sightings and related information are being compiled by University of Arizona researchers.
I found one of these plants yesterday at Saguaro National Park East. Today I added a new webpage to my Desert Botany site: For Matthiola parviflora photos, nontechnical identification tips, and instructions for how to report a sighting, visit this page:
