Cestrum plants can vary in size depending on the climate and growing conditions. In tropical climates, where they thrive, they can reach heights of up to 15 feet. These tall cestrums create a beautiful and impressive display with their open, summer flowering shrubs or vines. However, in areas where they experience freezing temperatures, cestrums tend to freeze back and are often kept as smaller shrubs that typically do not exceed five feet in height and width.
I have personally encountered cestrums in both tropical and temperate regions, and the difference in their size is quite noticeable. In tropical areas, where the climate is warm and conducive to their growth, cestrums can grow into large, sprawling shrubs or vines that can dominate the landscape. The height and spread of these plants create a lush and vibrant presence in gardens and landscapes.
On the other hand, in colder regions where cestrums are not as hardy, they tend to be smaller in size. The freezing temperatures can damage the plants, causing them to die back to the ground. As a result, they often regrow as smaller shrubs that are better able to withstand the winter conditions. These smaller cestrums still produce beautiful flowers, but their overall size is more compact and manageable.
It is important to note that the size of cestrums can also be influenced by other factors such as pruning and maintenance practices. Regular pruning can help control their size and shape, allowing them to fit into different garden spaces. Additionally, proper care, including adequate watering and fertilizing, can promote healthier growth and potentially increase the size of the plants.
Cestrum plants have the potential to grow quite large in tropical climates, reaching heights of up to 15 feet.

Pruning and maintenance practices, as well as environmental factors, can also affect the size of cestrums.
