Where to use it in a border
At around 45 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 7b, so check it suits your area before planting.
It appears in our lists of full sun, clay soil, wet soil, pollinator-friendly plants.
