Euphorbia mellifera – Planting & Care Guide

About Euphorbia mellifera

Euphorbia mellifera, commonly known as the Honey Spurge, is a striking evergreen shrub grown for its bold architectural form, attractive blue-green foliage and unique honey-scented flowers. In spring, large rounded clusters of bronze-green to yellow-green flowers emerge above the foliage, releasing a distinctive sweet honey fragrance that attracts bees and other beneficial pollinating insects.

Native to the Canary Islands and Madeira, this elegant shrub grows into a rounded specimen reaching approximately 1.5–2.5 metres tall with a spread of 1.5–2 metres. Its handsome evergreen foliage provides year-round interest, making it an excellent choice for Mediterranean-style gardens, coastal planting and contemporary landscapes. It performs particularly well in the mild climate of Ireland when planted in a sheltered, well-drained position.

Planting Guide

• Plant in full sun or partial shade.
• Choose a warm, sheltered location protected from cold winds.
• Prefers fertile, well-drained soil.
• Suitable for loam, sandy and chalky soils.
• Improve heavy soils by incorporating compost and horticultural grit before planting.
• Dig a planting hole twice the width of the root ball and the same depth.
• Carefully remove the plant from its pot and gently loosen the roots.
• Position the root ball level with the surrounding soil surface.
• Backfill with soil, firm gently and water thoroughly.
• Apply a light layer of organic mulch around the base, keeping it away from the stems.
• Space plants approximately 1.5–2 metres apart to allow room for mature growth.

Care & Maintenance

Euphorbia mellifera is a low-maintenance shrub once established.

• Water regularly during the first growing season.
• Once established, water only during prolonged dry periods.
• Avoid waterlogged soil, particularly during winter.
• Feed in spring with a balanced slow-release fertiliser.
• Mulch annually to retain moisture and improve soil quality.
• Remove weeds regularly from around the base.
• Water container-grown plants more frequently during warm weather.
• Protect young plants from severe frost during their first few winters.
• Wear gloves when handling the plant, as the milky sap can irritate skin and eyes.

Pruning

Pruning requirements are minimal.

• Remove faded flower stems after flowering by cutting them back to the base.
• Prune out any dead, damaged or weak stems in spring.
• Lightly shape the plant if necessary to maintain a balanced habit.
• Avoid cutting into old woody stems unless essential.
• Always wear gloves when pruning to avoid contact with the sap.
