Monardella villosa subsp. obispoensis is a native California subshrub in the Lamiaceae family, recognized by tufted growth, single flower clusters, white-woolly leaf undersides.

San Luis Obispo monardella is a California native shrub found in southern Coast Ranges and southern Central Coast bioregions in chaparral and oak woodland at elevations below 1,500 meters. Flowering from May to August, this plant produces white to lavender flowers in compact clusters 15 to 25 millimeters wide. Growing with ascending to erect stems 15 to 30 centimeters tall, the plant forms dense tufted or matted clusters with stems covered in both simple and branched hairs. Its narrow ovate leaves are 15 to 25 millimeters long, green on top and white-tomentose underneath, often appearing woolly and soft to the touch. The flower clusters emerge from unmodified leaves, creating a delicate and textural appearance in its native habitat.
