Euphorbia ceratocarpa

horned spurge

Product Image
This evergreen sub-shrub forms a tall, upright structure, typically reaching close to 2m (6ft) with a comparable spread. The subtle, slightly bluish-green foliage provides a sophisticated backdrop. Its unique, long-lasting yellow-green flowers are a horticultural marvel, appearing profusely from mid-summer right through to mid-autumn.

In milder UK climates, expect these blooms intermittently year-round, offering exceptional value for late-season arrangements. Euphorbia ceratocarpa is perfect for contrasting with rich, dark foliage plants or bold red and purple flowers, and thrives in well-drained, light soil. It becomes notably drought-resistant once established, making it a low-maintenance choice. Use the cut flowers as a vibrant addition to bouquets.

How to care for Euphorbia ceratocarpa:

When planting, it's generally not necessary to add compost or enrich the soil unless the soil is very poor, as this plant thrives in well-drained, moderately fertile soil. However, if the soil is particularly sandy or heavy, you can work in some well-rotted compost to improve structure and drainage.

Water thoroughly during the initial establishment period, but once settled in, it prefers drier conditions and should only be watered sparingly. Avoid waterlogged soils, as they can lead to root rot. Each stem is biennial, so will produce leaves in its first year and flower in its second. Once the stem has produced a flower it should be cut right back to its base, or to a point where there is new growth emerging, once the stem has faded and turned brown (typically late autumn/early winter). This will make way for lots of new, fresh shoots.

When working with spurges always wear gloves since the milky sap is poisonous and a potential skin irritant. Remove seedlings as they appear.
