Care essentials
Light
Thrives in full sun to partial shade; in NE Florida, full sun produces the most compact, tidy clumps, though afternoon shade is tolerated and reduces stress during peak summer heat.
Water
Drought tolerant once established; water regularly for the first growing season to develop deep roots, then reduce to supplemental irrigation only during extended dry periods.
Soil & Fertilizer
Adapts to sandy, clay, or loam soils as long as drainage is adequate; apply a slow-release balanced fertilizer once in spring. Avoid overwatering or soggy conditions, which can cause crown rot.
