Native to Western Australia, this small tree is excellent for small urban spaces, growing 10-20 ft in height and 6-15 ft in spread. It has an upright habit with an open, sparse crown. Agonis flexuosa (Willow Myrtle) has an attractive foliage of broad green leaves with a smooth texture. In summer, the tree is covered with white to off-white, fragrant flowers that attract bees and other beneficial insects. When blooming, its flowers give the tree a soft, romantic look.

This is a hardy drought-tolerant tree - once established, it only needs moderate amounts of water compared to other trees. Agonis flexuosa can tolerate salt, making it suitable for seaside gardens or areas exposed to salt spray. It performs best in full sun to semi-shade and is frost-hardy, growing well in USDA Zone 8-11.

When planting Agonis flexuosa, the soil should be well-drained, not too heavy and with a neutral pH. If you choose to grow it in a pot, you should use a well-draining potting mix, water frequently and add a layer of mulch as it helps to keep the roots cool and moist. In cold regions, it's best to keep the pot in a sheltered or sunny spot during the winter months to protect it from frost and cold winds.

Overall, Agonis flexuosa is a low-maintenance, versatile species that adds beauty and texture to any garden. Its fragrant flowers, attractive foliage and hardiness make it an ideal choice for temperate gardens that require a small, hardy tree.
