Where to use it in a border
At around 35 cm, it sits best toward the back of a border, or on its own as a focal point with room around it. Give it about 35 cm of room to spread, roughly 3 to the metre when planted in a drift. It is hardy across USDA zones 2a to 11b, so check it suits your area before planting.
It appears in our lists of shade.
