This is a good plant for the gardener who designs in the country style, with a flowery mixture of bedding plants in summer.semperflorens, which grows not more than 9 inches (23 cm) tall, and has small in slightly drooping clusters, is a natural choice for a window-box. The are white, pink or red, and bloom from mid-summer until cut down by frosts. It is more graceful and blends better with other plants than the large-flowered 8. x luberhybrida.
The white forms contrast well with heliotrope, pelargoniums, fuchsias, and other plants of vivid colour. The red and pink forms can create some horrid clashes, so think out your colour scheme carefully if you use them; the lovely plants in autumn, unless you want to keep them in the house. Early spring bulbs can be planted immediately in their place.
