Description

This easy care plant produces very pretty arching sprays of lavender blue daisy shaped flowers in autumn when there is very little else in the garden. It is a winner of the prestigious Award of garden Merit From The RHS for its garden qualities. It flowers for weeks on a bushy plant, and it is mildew resistant. It works well in mixed borders and attracts beneficial insects, such as birds and butterflies and bees, being a great source of nectar for them. It can also withstand approx -15 dec C and can also be grown in dry areas, being a good plant for areas which are naturally dry. It makes a good speciman plant, to grow in a container. It grows in fun sun but will also grow in partial shade.If you pinch the stems back before mid summer you can encourage a bushier plant with more flowers and this will also reduce the plant height. Divide the plant every 3-5 years.
