Where to use it in a border

At around 30 cm, it sits best along the front edge, where a low, spreading habit reads best. 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 5b to 9b and rated H5 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.
