Summary
Delphinium californicum, commonly known as California Larkspur or Coast Larkspur, is a semi-deciduous perennial herb that thrives in the coastal sage scrub and chaparral of Central California, particularly in areas with cool, moist winters and dry summers. It is endemic to California, where it contributes to the region’s biodiversity. This wildflower features tall, erect stems that can exceed one meter in height, often approaching two meters. The top of the stem boasts a large inflorescence, typically containing over 50 flowers, each borne on a pedicel several centimeters long. The sepals form a forward-pointing cup at the mouth of the tubular flower, with the longest sepals reaching about a centimeter and the spur extending up to two centimeters. Flower color ranges from white to greenish-white to light lavender, blooming from late spring to early summer.
California Larkspur is valued for its vertical accent in garden designs and its ability to attract pollinators such as bees and butterflies. It is often used in native plant gardens, borders, and wildflower meadows. While it prefers full sun to part shade, it is drought-tolerant once established, requiring only low amounts of water. It thrives in well-draining soils and can adapt to a variety of soil types, though it prefers those with medium drainage. Gardeners should be aware that all parts of the plant are toxic if ingested, and it should be handled with care to avoid skin irritation.CC BY-SA 4.0
