Delphinium nudicaule, commonly called red larkspur or scarlet larkspur, is a perennial wildflower native to western North America. It grows from a clump of finely divided, fern-like basal leaves and produces tall, slender stems that bear bright red to orange-red tubular flowers, often with a yellow throat. Blooming in summer, these flowers are adapted for hummingbird pollination, with a backward-extending spur typical of larkspurs. The plant prefers well-drained soils in open woodlands, rocky slopes, and montane meadows, thriving in full sun to partial shade. It reproduces by seed and basal rootstocks, forming small colonies over time. Its colorful flowers and resilience make it an attractive choice for native plant gardens and wildlife-friendly landscaping.
