Gallesia integrifolia, commonly known as Pau D’alho or Ivorywood, is a deciduous tree native to the tropical rainforests and gallery forests of South America. It exhibits a moderate growth rate and typically reaches a height of 20-50 feet (6-15 meters) with a spread of 10-30 feet (3-9 meters). The tree is notable for its pinnate leaves and clusters of small, fragrant greenish-white flowers that bloom in the spring and summer, followed by small, non-edible fruits. The bark is smooth and light gray, and the tree is sometimes used for its aromatic wood.

Pau D’alho is valued for its ornamental features, including its fragrant flowers and attractive foliage. It is suitable for use in tropical and subtropical gardens, and due to its moderate size, it can be planted in urban settings as a street tree or in public parks. It requires full sun to part shade and thrives in a range of soil types, including clay, loam, and sandy soils, as long as they have medium drainage. Regular watering is necessary to keep the tree healthy, especially in drier climates. While generally pest-free, it can be susceptible to root rot if overwatered or planted in poorly drained soils.CC BY-SA 4.0
