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 6a to 10a and rated H6 by the RHS, so check it suits your area before planting.

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

Border Builder uses Wallflower's height, spread, soil, bloom months and companions to place it in a full border plan for your own conditions, on iPhone and iPad.
