Chrysanthemum
Chrysanthemum morifolium
Chrysanthemums, commonly known as 'mums', are cherished flowering perennials known for their stunning variety of colors and intricate petal shapes. While often used as seasonal decor, they can thrive as indoor plants with the right care. They are famous for their ability to filter indoor air pollutants, though they are primarily valued for their dense, showy blooms that range from white and yellow to deep burgundy and purple.

Light Requirements
Indoor mums require bright, indirect sunlight. Place them near a south or west-facing window, but shield them from intense direct afternoon sun which can wilt the flowers.
Watering and Feeding
Keep the soil consistently moist but never soggy. If the soil dries out completely, the plant may drop its buds. Feed your mum with a liquid fertilizer every 14 days while it is actively growing.
Temperature and Air
They prefer cool to average room temperatures between 60°F and 70°F. High heat will shorten the life of the blooms. Ensure good air circulation to prevent powdery mildew.
Maintenance and Reblooming
Remove spent flowers immediately to encourage new buds to open. To get a mum to rebloom indoors, you must simulate seasonal changes by providing 14 hours of total darkness each night once the plant has finished its initial flowering cycle.
Common Issues
Watch for aphids and spider mites. If the leaves turn yellow, you may be overwatering or the plant may not be receiving enough light.
