Delphinium parishii, commonly known as Desert Larkspur, is a deciduous perennial herb native to the arid desert washes, rocky slopes, and chaparral of the Southwestern United States and Northern Mexico. It typically grows to a height of 17–60 cm, though it can occasionally reach up to 100 cm. The plant features palmately lobed leaves that often shrivel by the time of flowering. Desert Larkspur is notable for its striking flowers, which vary in color across its range: dark blue to purplish near Joshua Tree National Park, sky-blue in the eastern and northern parts of the desert, and pink in some areas of California. The flowers are multi-hued, with upper true petals often white, a nectar spur that is darker blue or purple, and sepals that are light blue with darker tips. The flowering season spans from April to June, and the blooms are highly attractive to pollinators such as bees and butterflies.

Desert Larkspur is valued for its drought tolerance and vibrant flowers, making it a suitable choice for xeriscaping, rock gardens, and native plant gardens in arid regions. It thrives in full sun and requires minimal water once established, preferring well-drained soils. While it is relatively low-maintenance, it can be susceptible to fungal diseases if grown in conditions that are too moist or humid. Gardeners should be aware that all parts of the plant are toxic if ingested, so it should be planted with caution in areas accessible to children and pets.CC BY-SA 4.0
