Diplacus brevipes, commonly known as widethroat yellow monkeyflower, is an annual herb that is native to the chaparral, coastal sage scrub, and oak woodlands of southern California and Baja California, often flourishing in open areas that have been recently cleared by wildfire. It typically grows to a height of 2-31 inches. The plant features an erect stem covered in fine hairs and lance-shaped to oval leaves that can reach up to 3.5 inches in length. The flowers are notable for their bright yellow corolla, which can be up to 1.2 inches long, with five distinct lobes at the mouth, and a tubular throat that is encapsulated in a hairy calyx with pointed tips. The flowering season is from late winter to early summer, and the flowers are quite showy, attracting pollinators such as bees.

Widethroat yellow monkeyflower is appreciated for its vibrant flowers and its ability to thrive in disturbed sites, making it a good choice for restoration projects and wildflower gardens. It is also used in border planting and as a ground cover in appropriate climates. This plant prefers full sun to part shade and requires well-drained soils. It is drought-tolerant once established, making it suitable for xeriscaping. While generally low-maintenance, it can be susceptible to fungal diseases in wet conditions.CC BY-SA 4.0
