How to Grow Mexican Hat
Ratibida columnifera
Mexican Hat thrives in full sun and poor, well-drained soil — rich or moist conditions encourage floppy growth. Plant in spring or autumn and water until established; after that it is remarkably drought-tolerant. The tall central cone surrounded by drooping yellow or red-tinted petals blooms from midsummer into autumn. Leave seed heads for birds and self-seeding; cut back in early spring before new growth emerges.
Yearly Lifecycle
Care Essentials
No feeding needed. Ratibida thrives on neglect — fertiliser encourages floppy growth.
Watch For
- Aphids on new shoots
- Powdery mildew in dry conditions
Companions
Echinacea, Rudbeckia, Native grasses, Salvia
Care Requirements
Light
Full sun; at least 6 hours direct sun per day
Requires full sun for the best flowering and strongest stems. Will tolerate partial shade but flowering declines and plants become floppy.
Spacing
40cm apart; self-seeds to fill gaps
Space plants 40cm apart. They self-seed freely and will naturalise in open sunny spots over time.
Watering
Low water needs once established; drought-tolerant
Water regularly until established, then leave largely to its own devices. Ratibida is extremely drought-tolerant once rooted in.
Fertilizing
No feeding; poor soil preferred
Do not feed. Fertiliser produces excessive leafy growth at the expense of flowers and causes stems to flop.
Pruning
Deadhead in summer; cut back in early spring
Deadhead spent flowers throughout summer to extend bloom. Cut stems back to the base in early spring before new growth appears.
Mulching
Mulching not needed; good drainage is key
Avoid heavy mulching over the crown. Good air circulation and drainage are more important than moisture retention for this plant.
Growing Tips
Poor soil is best
Avoid rich or fertile soil — it causes floppy, weak stems. Plant in average to poor, well-drained ground for the strongest upright growth.
Deadhead to extend bloom
Remove spent flower heads regularly to prolong the flowering season well into autumn.
Leave seed heads for winter
Allow some seed heads to remain through autumn and winter to self-seed and feed birds.
