Where to use it in a border

At around 60 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 3a to 9a and rated H5 by the RHS, so check it suits your area before planting.

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

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