Careya arborea is a deciduous tree native to Southeast Asia. It makes an excellent ornamental planting with its tall height of up to 20 feet and its white or off-white flowers with shades of red and crimson attracting butterflies and hummingbirds. Its ethnomedical uses are extensive, and the shoots and flowers are often served in traditional Thai dishes such as Nam Phrik and Vermicelli Fish Curry.
This tree prefers full sun or semi-shade and does best in slightly acidic and well-drained soils. Regular water helps its growth and quickens its development. It grows best in USDA Zones 9-11, but can also be grown in colder regions in a large pot. For best results, the pot should be kept outdoors to maintain a slightly cool temperature and an environment similar to its natural habitat. If the tree is planted in colder regions, the roots should be well insulated, and water should be provided regularly in order to ensure a healthy growth. The trunk should be protected with a layer of mulch in winter to protect its roots.
Careya arborea is a fantastic addition to any garden or landscape due to its beauty, size, and easy care. It is a great choice for those looking for a large, deciduous tree, with exotic colored flowers sure to attract the attention of both locals and visitors.
