Gardenia scabrella, also known as the Star Flower, is a hardy, medium-sized shrub or small tree originating from Australia. Growing up to 5 to 10 feet tall shrub or 10 to 20 feet tall tree, it produces white to off-white fragrant flowers with a subtle star shape that emits a sweet scent. Gardenia scabrella is best suited to USDA zones 9-11, and it prefers a sunny location with regular water application.

Gardenia scabrella should be given a hole that is twice as wide as the root ball and just as deep. The surrounding soil should be enriched with compost before planting to help promote healthy growth. For best results, a slow-release fertilizer should be worked into the soil at the bottom of the planting hole.

Gardenia scabrella needs regular watering, particularly during periods of extended heat. Pruning is also important, as the plant should be trimmed after the flowering season to keep it in its desired shape and size.

In colder regions where winter temperatures dip below freezing, Gardenia scabrella can be grown in a pot or container indoors. To ensure the plant survives the winter, the container should offer proper drainage and should allow for the soil to dry out slightly between waterings. A slow-release fertilizer should be added to the soil during winter months to maintain the health of the plant.
