Best uses

Best used as a specimen tree.

Physical characteristics

An evergreen tree that grows to 3-5m tall and wide.

Flowers and foliage

Large single white flowers with wavy edges and yellow stamens bloom from April to September. The dark glossy green leaves turn red before maturing and falling off.

Preferred site

Prefers full sun to part shade and moist, well-draining soil.

Preparation for planting

Always choose healthy, well-grown plants. Plant after autumn rains when the soil is moist and warm, allowing trees and shrubs to become established before winter. Planting success is often improved on clay soils by adding gypsum and extra topsoil and forming raised beds. Incorporate coarse sand, bark and compost to improve soil structure. Before planting, ensure that the root ball is saturated and remove planter pot with minimal root disturbance. Trim any broken roots or branches and plant at the same level as in the container. Long term, slow-release fertilisers may be added at this stage. As soil is placed in the prepared hole, tread firmly to bring soil in close contact with the root ball. Water thoroughly, making sure that moisture penetrates to the depth of the root ball.

Tall plants and those in windy positions require staking to stabilise the root ball until established. Position the stakes in the hole before planting and place the plant between them. Use wide ties that hold securely without chafing. Tie firmly but allow room for the trunk to increase in girth. This allows the plant to move a little in the wind, encouraging the development of a strong root system without the risk of chafing or root damage.

Maintenance tips

Apply mulch annually to suppress weeds and conserve moisture. Organic material, such as sawdust and bark, contribute to soil structure. However, make sure to keep mulch away from plant stems. The first summer and autumn after planting are critical for young plants, so water thoroughly during dry periods. A light application (50g/m2) of general-purpose fertiliser in spring is beneficial. Sprinkle evenly and work into the top 2 to 3cm of the soil, taking care not to damage the delicate roots. Check stakes and ties for chafing and constriction and remove as soon as plants are strong enough to withstand winds without damage.

Little or no pruning is required until the tree gets large enough to need reducing in size.

Interesting facts and tips

The flowers resemble those of the closely related camellia. However gordonia flowers do not go brown on the plant instead they drop off and land on the ground with the stamens facing upwards resembling a carpet of fried eggs.
