Auranticarpa rhombifolia is a rainforest tree of eastern Australia. Known as the diamond leaf pittosporum, this tree is planted in many parts of Australia as an ornamental. The white flowers and orange fruit make it a most appealing street or garden tree. Other common names include hollywood, diamond leaf laurel, white myrtle and white holly. Australian botanists recently examined the large genus Pittosporum and decided the more northerly examples are significantly different from those in the south. Subsequently, a new genus was created Auranticarpa, which means "gold fruit". The range of natural distribution is on red–brown basaltic soils from Richmond River, New South Wales (28° S) to Forty Mile Scrub National Park (18° S) in tropical Queensland.
The diamond-leaf pittosporum is resistant to disease and typically isn’t susceptible to many illnesses. When it comes to care, the plant is fairly low maintenance. Planted outdoors it needs only light watering, and larger specimens generally do not require pruning. Smaller plants, however, should be pruned after they have finished blooming. Diamond-leaf pittosporumt is suitable for anyone with outdoor space, such as a garden or deck, and does not demand a great deal of care experience.
How to keep Auranticarpa Rhombifolia.
Light
Diamond-leaf pittosporum naturally occurs in settings like forest understories or rocky terrain, where it grows in shaded conditions. It prefers partial sun but can tolerate both full sun and full shade, illustrating its versatile, hardy nature.
Water
The Diamond-leaf Pittosporum flourishes in subtropical environments where there is a balance between moisture and dryness. It has a moderate tolerance for drought and thrives best with consistent humidity levels. Watering every two weeks aligns with its natural cycle and is recommended. Ideally grown outdoors, the plant benefits greatly from rainwater during the growing season to maintain optimal hydration.
Temperature
Diamond-leaf pittosporum adapts well to heat, tolerating high temperatures and wide temperature swings. In hot weather, you should monitor watering and provide suitable shade to prevent sunburn. On the other hand, it is not very tolerant of cold. It can handle mild chill, but very low temperatures can cause frost damage.
Fertilizer
Timing is important for fertilizing Diamond-leaf pittosporum. Apply fertilizer in early spring and continue once a month until early summer. Fertilizer encourages attractive blooms and supplies energy during both dormant and active growth phases.
