Geraldton wax (Chamelaucium uncinatum) is an attractive large shrub, growing 5-10 feet tall, with fragrant narrow leaves, up to 2 inches long. It produces circular flowers that typically range between 1 and 2 inches in diameter, and can appear in shades of pink, white, off-white, blue, lavender, purple and yellow to orange. The flowers last for well over a week when cut.
Native to Western Australia and grown in USDA Zones 9-11, Geraldton wax is known for its ability to survive in dry climates but also does reasonably well in more humid regions. It can tolerate periods of extended drought and requires full sun and moderate amounts of water, with occasional deep watering during the summer months.
In order to ensure successful growth, it is important to plant Geraldton wax in a very well-drained, sandy soil and in a sunny or semi-shaded area. Pruning the shrub back by one-third each year can help it to flourish.
In cold regions, Geraldton wax can also be grown successfully in a pot. The pot should be filled with a well-draining soil, such as perlite, and the container should be positioned in an area that receives sunlight for most of the day. It is important to keep the soil lightly moist and water the potted shrub when the top inch of soil feels dry. During the cold winter months, it should be protected from frosts and strong winds.
