Description
Hibiscus rosa-sinensis 'Californian Gold' is an evergreen shrub celebrated for its large, single golden apricot-yellow flowers with a pink centre, creating a striking contrast against its thick, green, glossy leaves. In Perth's climate, this hibiscus thrives outdoors, making it ideal for garden beds, informal hedges, or as a focal point in the landscape. It prefers full sun and well-drained, fertile soil, reaching heights of 1.8 – 2.4 M and widths of 1.2 – 1.8 M.
To maintain its health and promote prolific flowering, water the plant regularly, especially during the warmer months, ensuring the soil remains moist but not waterlogged. Apply a balanced, slow-release fertiliser in early spring (Djilba) and again in early summer (Birak) to support vigorous growth. Prune lightly after the main flowering period to encourage a bushy habit and remove any dead or damaged branches. Mulching around the base can help retain soil moisture and regulate temperature. Be mindful of potential pests such as aphids and hibiscus beetles; regular monitoring and appropriate treatments will keep the plant healthy.
