A variable plant that forms neat clumps of foliage in spring which dies back as the upright flower stems emerge in mid summer. The flowers are very pretty nodding violet-blue bells that form in loose trusses at the top of the stem. This is an elegant plant that is easy to grow. It is a native of dry grassy slopes throughout Europe and the UK so it looks right at home in naturalised or prairie-style planting schemes.

• Garden care: Protect the tender foliage from slug-damage using environmentally friendly slug pellets or beer traps. During the growing season water freely and apply a balanced liquid fertiliser each month.
