Plant Needs
Sunlight
Full sun to partial shade; thrives in coastal, windy conditions and tolerates reflected sunlight from concrete or water
Watering
Water deeply but infrequently; allow top 5–7 cm of soil to dry between waterings to prevent root rot
Temperature
Hardy to 10°C; avoid prolonged frost exposure; prefers warm, mild coastal temperatures
Characteristics
- Leaf: Pinnately compound, silvery-gray leaves with 5–11 oval leaflets, covered in fine white pubescence to reduce water loss
- Flower: Bright yellow, pea-shaped blooms arranged in dense terminal racemes, producing a mild, sweet fragrance
- Stem: Grayish-brown, densely hairy stems that mature to woody, rigid growth
Care Guide
Watering
Water every 5–7 days during dry spells; maintain consistent moisture without waterlogging
Fertilization
Apply a balanced, slow-release fertilizer once in early spring. Do not over-fertilize, as this can reduce flower production and increase foliage growth
Composted banana peel tea：Steep fully composted banana peels in water for 24 hours, dilute 1:20 with water for root drenching; discard solid peels to avoid attracting pestsPruning
- Remove dead, damaged, or diseased branches in early spring to encourage new growth
- Thin dense inner foliage to improve airflow and reduce fungal disease risk
- Trim back spent flower racemes after blooming to promote a compact, rounded shape and potential reblooming
