Where to use it in a border

At around 70 cm, it sits best through the middle of a border, between taller structure behind and edging in front. Give it about 40 cm of room to spread, roughly 2 to the metre when planted in a drift. It is hardy across USDA zones 3a to 8b 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.
