This is a great favourite among hardy border plants. if the dead flowers are picked off regularly the plants will bloom throughout the summer from early July. The Canterbury bell is useless after it has flowered, therefore a fresh stock of plants must be raised each year Seeds are sown in May in a box of fine soil in a frame, and in due course the seedlings are planted on a reserve border; there they remain until October, when they are set where they are to flower the following year. Any plants which do not bloom then should be left undisturbed: they will form giant specimens the next year.
There are many varieties of Canterbury bell —single, double and cup and saucer flowers in purple, rose, lavender, white and other shades. All thrive in ordinary soil that has been well cultivated. Those who have no room for raising seedlings may buy plants in autumn or spring.
