Chrysanthemums are perennials and come in a huge range of colours and sizes. A welcome shot of colour when many plants are already dying down for the winter. Smaller ones are great for pots. They are great cut flowers and have a long vase life.
Some are hardy and will survive the winter in the garden in milder areas. Others are half-hardy and will need to be lifted and put in a dry, frost-free greenhouse or shed to over winter.
They all like a sheltered sunny site. Taller varieties may need some support.
