Mustard, a non-native plant that is more like a weed than a wildflower, is nevertheless blooming profusely on grassy slopes all along the coastline of San Diego County. On certain hillsides with moist ground, mustard plants may reach ten or more feet in height. An old story, probably apocryphal, tells of the early padres scattering mustard seed along the El Camino Real so that the bright yellow mustard blossoms would help missionaries find their way in future spring seasons.
