Hibiscus trionum is a rarely seen hibiscus, bearing pale green flowers with a crimson, almost black centre, and delicate paper lantern seed pods. Each flower lasts only a day, and often flowers only when the sun shines, but as a fast grower with a prolific blooming potential throughout summer until the first frosts, it's well worth growing.

Unlike some hibiscus varieties, Hibiscus trionum is easy to grow, and is perfect for growing as a filler plant in a sunny ornamental border, or displayed as the main feature of a patio container. It forms a compact mound of dark green leaves, which form the perfect backdrop for its exquisite flowers. For best results, grow in fertile, moist but well-drained soil, in full sun.
