Description

Conocarpus erectus, commonly known as Buttonwood, is a versatile and hardy tree that thrives in coastal areas. It features leathery, oblong leaves with a gray-green tint and produces small, ball-like clusters of flowers that develop into distinctive, round seed heads. This evergreen tree is often found in wetlands or along coastal dunes, where its strong, salt-tolerant nature makes it ideal for tough environments. Buttonwood can grow up to 30 feet tall, making it a great choice for larger landscapes or as a focal point in coastal gardens. Its dense foliage provides excellent shade and privacy, while its bark has a unique texture that adds interest to the garden.

Light requirements

Buttonwood trees thrive in full sun and need at least 6 hours of direct sunlight to grow vigorously. While it can tolerate partial shade, its growth may be slower and less dense in shadier spots. A sunny location encourages its characteristic thick foliage and improves its ability to withstand wind and salt, making it an excellent choice for coastal gardens or areas exposed to harsh conditions.

Soil preferences, including pH and drainage

Conocarpus erectus prefers well-draining, slightly acidic to neutral soils with a pH range of 6.0 to 7.5. It is highly tolerant of a variety of soil types, including saline, sandy, and loamy soils, which makes it particularly well-suited to coastal environments. It can also thrive in wet or flooded areas, making it ideal for rain gardens or other moisture-rich locations. Good drainage is essential, though, as waterlogged soils can cause root rot.

Water needs

Buttonwood is relatively drought-tolerant once established, but it grows best with regular watering, especially during dry periods. While it can handle occasional flooding or standing water, it should not be kept in constantly soggy soil. During the growing season, ensure the tree receives consistent moisture, but allow the soil to dry out between waterings. In drier months, water less frequently. Buttonwood is well-suited for coastal regions with unpredictable rainfall, as it can withstand saltwater and intermittent drought conditions.
