About This Plant

Light shade. Semi-evergreen. Arroyo Sweetwood was first selected by plantsman Lynne Lowery, growing in a dry gravel arroyo near Monterrey, Mexico. It may be a bit early to evaluate this recent introduction, but Arroyo Sweetwood has proven fast-growing and vigorous in Texas. Big specimens can be seen around Trinity University in San Antonio. It survived temperatures down to 8 degrees in Abilene. This non-native reseeds easily, so use with caution near natural areas.

Vanilla-scented white flowers appear in spring.

Maintenance

Some slight tip dieback can be expected in severe freezes (below 15 degrees). Pruning cuts should only be made at a bud or branch; in general, focus on minimizing the number of dead, damaged, or rubbing branches. As with any tree, remove no more than 25% of the canopy during any five-year cycle. Leave the upper 2/3 of any tree’s crown uncut to maintain a healthy specimen, never removing more than the lowest third of the tree in a single pruning period.

Mulch with about 2” of woodchips or pine bark wherever possible. (In general, a tree’s mulched area should be six feet at minimum.)
