Well known for its flamboyant flowers, the Hibiscus group to plants include small shrub-like plants up to large trees.
Maximum sun exposure will enhance flowers.
Ornamental Hibiscus cultivars grow best in a well fertilised soil that is kept irrigated.
For best flowers, fertilise with each spring and late summer with a complete fertiliser.
Pruning will maintain a manageable size and promote continual flowers.
