Chrysanthemums, widely known as 'Mums', are a popular plant during the autumn equinox season. The name of this magical plant comes from the Greek words 'Chrysos' meaning "Gold" and 'Anthos' meaning "Flower". Any garden witch can tell you that a mum's flowered petals have many magickal purposes within spell workings. Each mum's colors can be used for different magickal intentions too. Just below I have written down a generalized mum's color correspondence chart. This will help you a great deal with incorporating mum's into your spell workings.
Here is the chart:
Red - Love, Harmony, and stirring romantic passions in bedroom.
Yellow - Health, Joy/Happiness, and Cheer.
White - Purity, Peace, Truth
Bronze Colors - Happy Hearth/Home Environment
Purple/Amethyst - Can add strength or empowerment to Spiritual Psychic and Protection spell workings.
Another great tip, even if you don't use mum's within spell workings: Just placing a specific colored Mum in the home will still bring positive energies to the household. This is why mums are a magickal and popular flowered plant during the autumn equinox season.
