A dwarf, purple flowering shrub suitable for pots. Position: full sun Soil: fertile, well-drained soil Rate of growth: fast-growing Flowering period: July to September Hardiness: fully hardy Rich in nectar and irresistable to butterflies, the cone-shaped clusters of rich purple flowers, not only look great, but they'll also help sustain vital pollinators. A recently introduced hybrid, these plants are reliably compact, so they're perfect for placing at the front of the border - and they will also do really well when potted up and placed near a sunny entrance or patio. Garden care: Prune back hard in March, removing all of the previous year's growth to three or four buds.
