Leucadendron Information
Leucadendron plants are relatives of Protea plants. While more commonly known as a conebush, the plant’s Greek name is actually something of a misnomer. “Leukos” means white and “dendron” means tree, but while white Leucadendrons can be found, the plants are most popular for their vividly vibrant colors. Each stalk of the plant is topped with a large inflorescence – the flower itself is relatively small, while the brightly colored “petals” are actually bracts or modified leaves. These inflorescences can sometimes reach 12 inches (30.5 cm.) in diameter. Leucadendron plants have a shrub-like growth habit and usually reach 4 to 6 feet (1-2 m.) tall and wide.
How to Grow a Leucadendron
Leucadendron care is not difficult, as long as your growing conditions are right. Leucadendrons are not cold hardy and are only suited to outdoor growing in USDA zones 9b through 10b. As long as conditions are warm enough, however, having Leucadendrons in the garden is very low-maintenance. The plants are drought-tolerant, and only need to be watered during particularly dry periods. Water deeply once per week instead of lightly every day. Try to keep the leaves from getting wet, and space them so that the leaves don’t touch any other plants. This should help prevent disease. Plant your Leucadendrons in a well-draining spot with full sun. The plants don’t need extra fertilizer, though they prefer slightly acidic soil. They can be pruned back very heavily. After blooming, you can cut back the woody material to just above a node. This should encourage new, bushier growth. If you live outside their hardiness area, it may be possible to grow Leucadendron in a container that can be overwintered indoors or simply treat the plant as an annual in the garden.
