Florist's chrysanthemums are beloved fall-blooming perennials offering dense clusters of colorful flowers in nearly every hue except true blue. They thrive in full sun and make excellent cut flowers, though they require deadheading and occasional pinching for bushier growth.

Why grow it

Florist's chrysanthemums extend the perennial flowering season into autumn when few other garden plants are at peak bloom, making them valuable for sustained color. Compared to asters and other fall bloomers, they offer a wider palette of flower forms (single, double, pompom, daisy-like) and more reliable dense flowering with proper management. Their value as fresh-cut flowers is well-established, though this requires consistent deadheading and pinching during the growing season to develop the bushy habit needed for multiple flower stems.

Watch out for

These plants are prone to powdery mildew and spider mites under crowded conditions or poor air circulation, particularly in humid climates. They may require staking or support as they mature and flower, especially taller cultivars or those grown for cutting. Division every two to three years helps rejuvenate vigor and maintain plant health, as performance can decline without this maintenance.
