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 3a to 8b, so check it suits your area before planting.

It appears in our lists of full sun, clay soil, pollinator-friendly plants.
