The fan flower, Scaevola aemula, is a relative newcomer to American gardens. It comes from Australia, and blooms consistently from spring into fall. It has five petals spread in a fan-like shape and is sometimes referred to as the Half-Flower for this reason. Colors often include blue, pink, purple, and white with bright yellow and white centers. The fan flower is drought-tolerant, and can withstand salty coastal air without any issues.
Family
The fan flower is a member of the plant family Goodeniaceae, which has several genera native to Australia, New Zealand, and nearby islands. It is a perennial, meaning it will come back year after year, given the right conditions.
Meaning and Symbolism
The fan flower is a symbol of happy news. The fan-like petals are meant to represent enthusiasm and joy. In some cultures, the fan flower symbolizes an escape from reality and a quick transition from one stage of life to the next. In Native American culture, the fan flower is a symbol of protection from danger.
History, Mythology, and Religious Significance

The Celtic Druids believed the fan flower had healing powers and the Ancient Greeks used it in their Olympics ceremonies. In Hinduism, the fan flower is believed to bring long life and joy. In Christianity, the fan flower is a symbol of the Virgin Mary.
Flower Varieties and their Defining Characteristics
The fan flower is available in a variety of sizes and colors, all of which feature five frilly petals in a fan-like formation. The most common varieties of Scaevola aemula are:
- White fan flower (Scaevola aemula ‘White Fan Flower’): A small and delicate white flower with white petals.

How to Plant
When planting fan flower, choose a spot with full sun or partial shade, depending on the variety and climate. The soil should be loamy and well-draining and the pH should be between 6 and 7. Some varieties of fan flower can tolerate more acidic soils. Water regularly, making sure the soil doesn’t dry out completely. Plant in beds or containers and use a fertilizer that is high in phosphorus and potassium.
How to Pot and Repot
The fan flower is a fast-growing and prolific bloomer, so it’s a good idea to pot and repot regularly to ensure the plant maintains a healthy balance. When potting, choose a potting mix that is well-draining and enriched with organic matter. Place the fan flower in the pot, make sure the root ball is level with the top of the pot, and make sure there is room for the roots to expand. Repotting is done by removing the root ball from the pot, replacing the soil with fresh, nutrient-rich soil and transferring the plant back into the pot. Make sure to water well after repotting and then water regularly.
How to Prune
Pruning fan flower is essential for maintaining a healthy, attractive looking plant. The best time to prune is late spring or early summer. Start by deadheading faded flowers and remove any damaged, diseased or dead branches. Prune back branches to 1/3 of their original length. This will allow new growth to come in and promote healthy new flower production. Prune lightly, as fan flower doesn’t take pruning well and can be easily damaged.
How to Propagate
Propagating fan flower is easy and there are a few methods to choose from. Seeds can be planted directly into the ground or in pots and should be covered lightly with soil and watered regularly. Softwood cuttings can also be taken from tips of branches in the summer and gently pushed into moist soil. Both seeds and cuttings should be kept in warm, sunny areas.
Common Pests and Diseases
The fan flower is relatively disease-resistant, but there are some pests that can cause damage. Aphids and mites can suck sap and nutrients from the fan flower and can weaken the plant. To prevent pests, keep the fan flower in a well-ventilated spot and use an insecticidal spray to ward off potential pests. Diseases to watch out for include root rot and powdery mildew, and can be prevented by avoiding overcrowding, watering at the base of the plant, and pruning branches to increase air circulation.
