Diplacus nanus, commonly known as dwarf purple monkeyflower, is an annual herb native to the chaparral and open woodlands of California, extending into the Northwestern United States, including Oregon and Montana. It is often found in moist, well-drained soils in open areas, such as meadows and along streams. This low-growing plant typically reaches up to 4 inches in height and has a sprawling or erect habit. The leaves are hairy, purple-green, and oval to oblong in shape. From late spring to early summer, it produces showy, tubular flowers that are typically magenta or purple with two distinctive yellow stripes in the throat, although some may be entirely yellow, adding a splash of color to the garden.

Diplacus nanus is valued for its vibrant flowers and compact size, making it suitable for rock gardens, borders, and as a ground cover in areas with similar climates to its native habitat. It thrives in full sun to part shade and prefers moist, well-drained soils. While it is relatively low maintenance, it may require additional water during dry periods. In cultivation, it can be used to attract pollinators such as bees and butterflies. However, gardeners should be aware that it may self-seed and spread if conditions are favorable.CC BY-SA 4.0
