About Cardinal Tea Tree
Botanically, Leptospermum 'Cardinal' is a shrub in the Myrtaceae family, native to Australia. It reaches around 2 m tall and 1.5 m wide at maturity, with evergreen foliage. Red flowers appear in spring.
Where to grow Cardinal Tea Tree
Cardinal Tea Tree suits warm-temperate, Mediterranean, subtropical and cool-temperate climates and grows best in full sun. It is frost hardy and shrugs off cold winters. It also tolerates salt-laden coastal winds, is a genuinely water-wise choice and is suitable for bushfire-prone (BAL) gardens.
Soil & planting
Cardinal Tea Tree does best in free-draining and sandy soil. Plant into well-prepared ground, firm the soil around the roots and water deeply to settle it in. For a screen, space plants about 90 cm apart.
Watering & feeding
Cardinal Tea Tree is happy on low water, so once its roots are down it needs little supplementary water. As an Australian native, feed it only with a low-phosphorus native fertiliser. In its first year, water deeply once or twice a week to settle the roots in, then taper off as it establishes.
Pruning & care
Prune Cardinal Tea Tree after flowering to keep it compact and encourage the next flush of blooms. It clips well, so trim two or three times a year for a formal finish. Overall it is low maintenance.
Using Cardinal Tea Tree in the garden
Cardinal Tea Tree earns its place for a feature or specimen planting, a fast screen or informal hedge and feeding bees and pollinators.
Companion planting & design
For a cohesive, low-care bed, pair Cardinal Tea Tree with other plants that enjoy the same happy on low water and warm-temperate climate. Repeat it through a border to tie the planting together and give a sense of rhythm. It combines naturally with other Australian natives in a habitat or water-wise garden.
