Where to use it in a border
At around 25 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 6a to 10b and rated H5 by the RHS, so check it suits your area before planting.
