Euphorbia — the quiet backbone of a Suffolk border

There is a moment in late May when the tulips are gone, the roses have not yet begun, and the border needs something to hold its nerve. Euphorbia is the plant I trust for that fortnight. The acid-green bracts read as flower from a distance, and they carry across a bed better than almost anything else at that time of year.

Why I keep planting it

Euphorbia is generous without being loud. It never asks for the front row. It sits behind the geraniums, weaves between the roses, softens the base of a shrub, and — when it is well placed — makes the plants around it look better than they otherwise would.

Once established, most of the perennial euphorbias are patient with drought, which matters on the sandier soils around Mendlesham and Debenham. I rarely water an established clump, even in a dry June.

A note of caution

The milky sap can irritate skin and eyes. I wear gloves when cutting it back, and I never do that job in strong sun. Worth knowing before you plant it near a path where children play.

How I place it

• In groups of three, threaded through a border rather than clumped in one spot.
• Behind hardy geraniums, so the geranium foliage hides the tired base later in summer.
• Against the warm stone of a wall, where the acid-green catches the low evening light.
• Cut back hard after flowering — new growth usually returns within weeks.

Euphorbia will not win a plant show. It is not that kind of plant. But it is one of the few that quietly makes everything else in the border look intentional.

Every garden is unique. The ideas shared in The Bon Blog are based on my experience working in Suffolk gardens. Your own garden may behave differently depending on its soil, aspect and local conditions.
