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 30 cm of room to spread, roughly 3 to the metre when planted in a drift. It is hardy across USDA zones 5a to 9b and rated H6 by the RHS, so check it suits your area before planting.

It appears in our lists of shade, acid soil, pollinator-friendly plants.
