Plumeria flowers typically bloom in cycles or waves during the active growing season. Each blooming cycle may last for several weeks, depending on the variety and growing conditions. After a blooming cycle ends, the plant may take a brief rest period before producing another wave of flowers. The number of blooming cycles per season can vary among cultivars and locations. Regular deadheading of spent flowers and providing optimal growing conditions can promote multiple blooming cycles, ensuring a continuous display of colorful and fragrant flowers throughout the growing season.
