Chrysanthemums or “mums” as they are popularly known, are traditionally given to mums on Mother’s Day in Australia. In Asia, they symbolize birth and rebirth, and given as gifts for both baby showers and funerals, though the colour influences its meaning. Red is universally known as the colour of love, and this holds true here too, yellow represents sorrow and white is devotion, if that helps you choose a colour.
They are great flowers for indoors, with flowers lasting weeks, which is surely a symbol of happiness and longevity! Keep them in a sunny spot inside, or bright spot outside and they will hold their flowers till mid-June, by which time you can plant them outside in a well-drained position in full sun and they will flower again next autumn.
