Sugarbush Protea Growing Guide

Protea repens, Protea susannae, Protea compacta and hybrids

Crop Rotation Group

Miscellaneous ●

Soil

Fertile, well-drained soil enriched with plenty of compost or other organic matter.

Position

Full sun.

Frost tolerant

Cold tolerance is limited for this semi-tropical shrub. Sugarbush is injured by winter temperatures below -4°C (25°F), so the plants grow best in climates with suitable winters.

Feeding

In early spring, cover the root zone with rich compost topped by a layer of organic mulch.

Spacing

Single Plants: 2.40m (7' 10") each way (minimum)
Rows: 2.40m (7' 10") with 2.40m (7' 10") row gap (minimum)

Sow and Plant

Set out purchased plants at any time except the hottest part of summer or the coldest part of winter, setting plants at the same depth they grew in their containers. Water regularly to encourage new root development during the first year after planting. In containers, use one plant per 35 cm (14-inch) pot.

Notes

Native to South Africa, sugarbush protea is valued by plant collectors for its large, exotic blossoms that appear in the warm season. The nectar was once collected and processed into syrup. Sugarbush is challenging to grow outside its native range, but plants are often successful in Southern California, Australia and warm Mediterranean climates.

Harvesting

Sugarbush blossoms are hugely popular as cut flowers, and trimming off spent flowers also encourages the plant to produce more blossoms. Sugarbush can be pruned at any time to control the plant’s size.
