How to Grow Fremontodendron
Fremontodendron californicum
Fremontodendron is a fast-growing California native shrub or small tree covered in large, saucer-shaped golden-yellow flowers from late spring through summer. Extremely drought-tolerant and suited to hot, dry sites with excellent drainage. It resents summer watering and clay soils. The stems and leaves are covered in irritating stellate hairs, so wear gloves when handling. Plant against a warm wall for best results in cooler climates. Minimal pruning needed.
Yearly Lifecycle
Care Essentials
Fremontodendron rarely needs feeding. Avoid fertiliser which promotes soft growth vulnerable to frost. If soil is very poor, a light top-dressing of grit and leaf mould in spring is sufficient.
Watch For
- Root rot from overwatering or poor drainage
- Frost damage on young growth
- Skin irritation from stellate hairs on stems and leaves
Care Requirements
Light
Full sun, warm wall ideal
Requires maximum sunlight. In cooler climates, plant against a warm south or west-facing wall for best flowering and frost protection. Will not thrive in shade.
Watering
Do not water once established
Fremontodendron resents summer watering. Water only newly planted specimens to establish. Once settled, it is extremely drought-tolerant and actively dislikes irrigation.
Fertilizing
Rarely if ever needed
Avoid fertiliser which promotes soft growth vulnerable to frost. On very poor soils, a light top-dressing of grit and leaf mould in spring is sufficient.
Pruning
Light trim after flowering if needed
Prune lightly after flowering to control size. Wear gloves and long sleeves as the stellate hairs are highly irritating to skin. Avoid cutting into old wood.
