Native California perennial in the Ranunculaceae with blue flowers and upward-pointing spurs, about 8–24 inches tall, prefers part shade, grows in grassy and woodland habitats, and blooms in spring, attracting swallowtail butterflies.
Common Names
Spreading Larkspur, Zigzag Larkspur
Summary
Native to California, this perennial herb grows in grassy and woodland habitats on dry slopes in sun or shade and typically reaches about 2 ft tall. It bears blue to purple flowers with upward-pointing spurs, commonly called Spreading Larkspur or Zigzag Larkspur, and attracts hummingbirds, bees, and butterflies.
Prefers bright direct sunlight with moderate temperatures and humidity; water only as soil partly dries to avoid waterlogging; requires well-draining loamy soil with pH slightly acidic to neutral and a compost mix; fertilize with a balanced 10-10-10 during spring and summer; repot every 2–3 years in early spring; propagate by seeds (late winter/early spring) or division (early spring or fall); after flowering, remove spent flowers and cut back stems to base; all parts contain alkaloids and are toxic if ingested; do not eat and handle with care.
