Which of the following is NOT a species recommended for planting under power lines?

The oak tree is not recommended for planting under power lines due to its potential height and spread as it matures. Oaks can grow quite large, reaching heights of 60 feet or more, which poses a significant risk of interference with power lines over time. When selecting trees for planting near utility lines, it is crucial to choose species that have a natural growth habit that will not encroach upon the overhead lines, thus preventing power outages and ensuring safety.

In contrast, the other species mentioned, such as crape myrtle, chaste tree, and red bud, are generally smaller in size and are more suitable for locations near power lines. These trees can thrive in such environments without posing a hazard to the utility infrastructure. When planning tree planting in urban and suburban settings, understanding the mature size and growth patterns of tree species is essential for proper placement and to avoid future conflicts with utility services.
