Calliandra californica
Light: Full sun for best flowering; tolerates light afternoon shade.
Water: Low water once established. Water deeply, then let soil dry between irrigations. Provide occasional supplemental water during prolonged summer heat for better foliage and flowering; water more frequently during establishment.
Soil: Well-drained sandy, gravelly, or loamy soil; tolerates alkaline desert soils. Avoid persistently wet soil and poorly drained planting sites.
Mature size: Approximately 4–6 feet tall and wide.
Bloom: Primarily spring through fall, with intermittent flowers during mild winter weather. Blooming increases with warmth and occasional deep watering.
Evergreen / deciduous: Evergreen in mild winters; may become partially deciduous after frost or prolonged drought.
Growth rate: Moderate; faster with supplemental irrigation during warm weather.
