Plant details

Gartensonne' really does bring a bit of sunshine to the late summer garden. Masses of frilly-edged yellow daisies top this back of the border perennial, which hums with bees when in bloom. You can enjoy the sunshine indoors as well, as the flowers are great for cutting. Those with sensitive skin should wear gloves when handling the plant as it can aggravate the skin. Plants will not reach their final height until their second year. To restrict their size, cut back to about 30cm (1ft) tall in May. This not only reduces their final height but will also delay flowering by a week or two. To propagate, divide plants in spring. Dividing in autumn often fails as the small plants produced die during the winter.
