Cycas revoluta, commonly known as the sago palm or king sago, is a captivating plant with a prehistoric appearance. Despite its name, it’s not a true palm but rather a gymnosperm, more closely related to conifers. This ancient species has adorned gardens and landscapes for centuries, prized for its elegant form and resilience.
Physical Characteristics
Trunk: The sago palm develops a sturdy, cylindrical trunk that can reach heights of up to 25 feet (7.6 meters). The trunk is typically covered in scars from old fronds, giving it a textured appearance.
Fronds: The most striking feature of the sago palm is its crown of large, pinnately compound fronds. These fronds are composed of numerous leaflets arranged along a central rachis. They are typically a deep green color and can grow up to 8 feet (2.4 meters) long.
Cones: Sago palms are dioecious, meaning they have separate male and female plants. Male plants produce cones that resemble elongated pineapples, while female plants develop cones with bright red seeds.
Cultivation and Care
Sunlight: Cycas revoluta thrives in full sun to partial shade. It can tolerate some periods of drought but prefers regular watering, especially during hot, dry weather.
Soil: The sago palm prefers well-draining soil that is rich in organic matter. It can be grown in containers or directly in the ground.
Fertilization: Fertilize sago palms once a year in the spring with a balanced fertilizer. Avoid over-fertilization, as it can lead to root damage.
Propagation: Sago palms can be propagated from seeds or offsets. Seeds require several months of stratification before planting, while offsets can be carefully removed from the base of the mother plant.
