Polyalthia australis, also known as Polyalthia, is a small tree native to Australia. It can reach a height of 10 to 20 feet, and its shiny, bright green leaves add tremendous aesthetic appeal when placed in the right environment. Polyalthia prefers full sun and regular watering, which allows the plant to produce its abundant clusters of fruit in the summer months.

This Australian native is hardy to USDA zones 9-11, making it an ideal choice for those wanting to grow this small tree in their garden. The plant thrives in humid conditions and requires rich, well-draining soil to produce its fruit. To ensure a healthy and vibrant Polyalthia tree, it is important to make sure the soil isn't too dense, as this can suffocate the roots.

When growing Polyalthia in cold climates, it is best to grow it in a pot. This offers more mobility and protection against extremes in temperatures. Planting the tree in a mix of peat moss, perlite, and potting soil is beneficial for the plant overall health. A quality potting mix ensures that the soil drains well and that the roots don't get waterlogged. Additionally, providing adequate light is essential for the tree growth, and it is important to water it regularly to keep the soil moist.

Polyalthia is a great choice for those wanting to add a unique, lush touch to their garden. With its shiny leaves and abundant clusters of fruit, adding this tree to one's landscape can be a great way to add instant interest and color. With the right environment and care, one can enjoy a healthy Polyalthia tree that adds beauty and charm to their home.
