Hosackia crassifolia var. otayensis, commonly known as Otay Mountain Lotus, is a perennial herb that is native to the chaparral and coastal sage scrub of Southern California, particularly in the San Diego region, including Otay Mountain. It typically grows to a height and width of 1-2 feet (0.3-0.6 meters), with a moderate growth rate. This plant is characterized by its sprawling habit and compound leaves with small leaflets. The flowers are yellow to orange, pea-like, and bloom in the summer months. They are moderately showy and attract pollinators such as bees.

Otay Mountain Lotus is valued for its drought tolerance and ability to thrive in poor, well-drained soils, making it suitable for xeriscaping and native plant gardens. It is often used in restoration projects and as an ornamental in dry, sunny areas. It requires minimal maintenance once established and is adapted to full sun exposure. While it is not commonly affected by diseases, it can be susceptible to root rot if overwatered or planted in poorly drained soils. It is important to note that this plant is not widely available in the nursery trade and may be of special interest to native plant enthusiasts or those involved in habitat restoration.CC BY-SA 4.0
