During the summer months, the Coyure Palm graces us with small, yellow flowers. Intriguingly, both male and female flowers emerge on the same inflorescence, a unique botanical characteristic.

Following the flowering phase, the palm produces round, bright red fruits with an orange endocarp, each measuring approximately 1/2 inch in diameter and containing a single seed.

Caring for the Coyure Palm

The Coyure Palm, while enchanting, is not particularly cold-hardy and can withstand temperatures down to 30°F. Therefore, it necessitates protection during cold snaps. It thrives in regions within USDA Zones 10a (with temperatures ranging from 30 to 35°F) to 11 (above 40°F).

To optimize its growth, this palm prefers consistently moist, well-drained soil, and it’s essential to avoid allowing the soil to dry out between waterings.

To ensure that the palm receives essential nutrients and to prevent nutritional deficiencies, it’s recommended to apply a high-quality palm fertilizer with a continuous-release formula twice a year during the growing season.

Propagation of the Coyure Palm is primarily achieved through seeds.
