Where to use it in a border

At around 120 cm, it sits best toward the back of a border, or on its own as a focal point with room around it. Give it about 90 cm of room to spread. It is hardy across USDA zones 3a to 9a and rated H7 by the RHS, so check it suits your area before planting.

It appears in our lists of full sun, clay soil, sandy soil, pollinator-friendly plants.
