Chrysanthemums are associated with autumn events -- homecoming and some of the memorial holidays -- and anchor the autumn landscape. Belonging to the aster/daisy family, chrysanthemums are among the most displayed and exhibited flowers in the world, with national societies in most developed countries. Mums are distinguished from other species in that each blossom, or bud, is composed of many individual flowers, and each floret is capabile of producing a seed. A single blossom can contain both male and female flowers. Because of the variety and understanding of the genius, cultivars are exhibited by being bonsai'd (root trained) to different forms, like floral poodles, so chysanthemum shows are entertaining and well attended.

- Plants need to be cut back three times before August 15 to assure bushy growth and to limit spring flowering.
Also known as hardy garden mums, Chrysanthemum comprise over 100 species of flowering perennials/half-hardy annual which bloom as the daylight hours shorten in Fall.
Easily propagated by cuttings, seed can be started indoors or directly in the field, in full sun to partial shade in well-drained soil as soon as the ground can be worked in Spring and again after June 21. Thin to 18 inches (45 cm.) apart.
Cut plants back three times during the spring and summer with the last cut on August 15 to encourage busy, compact growth.
Feed with nitrogen fertilizer until the last time you cut the plant back; then eliminate nitrogen, and feed with phosphorus and potassium.

Leaves can be eatened steam or , when new, used in salads, especially in Asian cuisine. Feverfew, a chyrysanthemum species, is used as a herbal remedy for migraine headaches. Pyrethrum, a red mum, is a natural source of insecticide and repellent, which attacks the nervous system of insects and inhibits mosquitos from biting. Pyrethrum power, while toxic to fish, is biodegradable and is not as harmful to mammals and birds than many synthetic compounds; it is biodegradable and breaks down upon exposure to light and is considered to be among the safe pesticides near food and edibles. Mum flowers are boiled to make a hot tonic in Asia and is used to recover from influenza. Mums are considered to be antibacterial.
Although these plants require pinching, each time the grow tip is cut retards growth; for maximum bloom, cut three times a season only, and only pinch growing tips.
