Care essentials
Light
Plant in full sun; at least 6 hours of direct sun is needed for compact upright growth and reliable flowering. Will tolerate brief partial shade but becomes floppy.
Water
Drought tolerant once established; water weekly when young, then reduce to once or twice per month. Avoid wet or poorly drained sites — root rot is the primary failure mode.
Soil & Fertilizer
Prefers lean, well-drained sandy or loamy soil; does not require fertilization. Excellent native choice for NE Florida dry flatwoods or meadow gardens. No pruning is needed — leave the dramatic basal rosette intact year-round.
