hello all. i have planted desert willows purchased from nurseries in the arid desert of southern utah, and the seeds volunteer readily in areas next to large rocks or rain runoff. while i have not eaten the prolific seeds, the blossoms attract hummingbirds, and local wildlife does collect and eat the seed. with your inspiration i will increase seed planting - they are taprooted plants and might do well to foster other trees. honey mesquite and screwbean mesquite also do well here, resistant to both heat and cold.
