Where to use it in a border

At around 90 cm, it sits best through the middle of a border, between taller structure behind and edging in front. 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 4a to 9b, so check it suits your area before planting.

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