A new, compact butterfly bush. Position: full sun Soil: fertile, well-drained soil Rate of growth: fast-growing Flowering period: July to September Hardiness: fully hardy This new butterfly bush puts on a dazzling display in summer, and it's ideal for smaller spaces. A dense shrubby plant reaching just 80cm or so, it's topped from midsummer to early autumn with conical sprays of lilac flowers, which attract butterflies in their droves. It flourishes in a sunny spot, and will quite happily live in a pot where space is at a premium. Garden care: Prune back hard in March, removing all of the previous year's growth to three or four buds.
