Southern California growing guide

• Light: Sun to partial sun.
• Mature size: Generally 2–4 feet tall, spreading about 6 feet wide.
• Water & drought: Water during establishment, then reduce irrigation. Drought tolerant, with supplemental water adjusted to soil and inland heat.
• Soil: Adaptable soils with drainage; avoid prolonged saturation.
• Growth: Fast-growing evergreen shrub with an open, airy structure. Soft pink flowers are especially associated with summer, with bloom duration varying by site.
• Wildlife: Flowers provide resources for butterflies and other visiting insects.
• Maintenance: Lightly shape wandering branches and remove spent stalks when needed. Retain some seed heads for seasonal structure.
• Landscape uses: Coastal borders, broad slopes, mixed habitat beds and informal groundcover groupings. Allow its mature spread instead of confining it to a narrow edging strip.
