Plants That Purify: Chrysanthemum

We all could benefit from a cheap and beautiful way to improve a home's indoor air quality. That's why I'm bringing you an ongoing series on house plants that are particularly good at purifying the air.

Next up in our series is the chrysanthemum.

Chrysanthemums are a beautiful, autumn flower, and if you decide to use garland chrysanthemums as a Thanksgiving centerpiece, they can do double duty in a salad, since the flowers are edible!

Although chrysanthemums are usually associated with outside fall flower beds, they also grow well in pots indoors. Chrysanthemums come in a wide variety of colors and prefer full sun, except when in bloom. Keep the soil from becoming compacted, and only water when the soil has dried out. Chrysanthemums flower as a response to short days and long nights, and while old plants are usually not rebloomed, you can grow new plants from cuttings. To force chrysanthemums to bloom, provide them with 14 hours of darkness for 10–12 weeks.
