Delavay Teaolive is a perennial ornamental shrub belonging to the olive family, native to Asia. It can attain a height and width of up to 12 feet, although its growth rate is quite slow. In the early spring, it showcases clusters of fragrant, tubular white blossoms.

This shrub is versatile regarding soil conditions and demonstrates drought resistance once established. While it can thrive in shaded areas, it produces the most flowers when exposed to full or partial sunlight. It can be shaped into a hedge through pruning or left to develop its natural shape.
