Arroyo Sweetwood
Myrospernum sousanum

This is an exceptional choice for a fragrant understory tree since it only reaches 12 to 18' in central Texas. It was originally discovered by Lynn Lowry in Mexico in the late 1980s. For unknown reasons, it has never been utilized sufficiently by landscape designers. It should be used often because this Sweetwood meets so many of the desirable traits we all seek in our residential landscape. Each spring the tree is covered in white, highly fragrant blossoms that are highly attractive to bees, butterflies and hummingbirds. The white blooms emit a strong scent of allspice or cinnamon. The plant's optimum soil is highly alkaline, but it thrives in almost any type except for sand. It is xeric and drought-tolerant when established. It is fast-growing and tiny when established. Contrary to what most reference works say about the habitat range of this tree, there are excellent mature specimens growing in public locations in Waco, Austin, and San Antonio, indicating the viability in USDA zones 8 through 10a.
