Fun Facts
- 🌱 Firecracker is native to California's dry slopes, canyons, and washes, and thrives in conditions that would kill most other ornamental plants.
- 🌱 The plant's brilliant red flowers evolved to attract hummingbirds rather than bees, as hummingbirds can see red wavelengths that insects cannot perceive as easily.
- 🌱 Once established, mature Firecracker plants can survive on rainfall alone in many climates, making them one of the most water-efficient flowering shrubs for western gardens.
