Where to use it in a border
At around 60 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 6a to 10b and rated H6 by the RHS, so check it suits your area before planting.
It appears in our lists of full sun, clay soil, pet-safe plants.
