Where to use it in a border
At around 100 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 45 cm of room to spread, roughly 2 to the metre when planted in a drift. It is hardy across USDA zones 5a to 9a and rated H7 by the RHS, so check it suits your area before planting.
It appears in our lists of full sun, sandy soil, chalk soil, pollinator-friendly plants.
