Where to use it in a border
At around 40 cm, it sits best along the front edge, where a low, spreading habit reads best. 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 2a to 11b and rated H2 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.
