Plant in well-drained soil in full sun or partial shade, where it forms neat evergreen mounds topped with lime-green flower bracts in early spring. It’s slightly more compact and hardy than Euphorbia characias, coping better with partial shade and cooler or moister conditions.

Once established, it’s drought-tolerant and low-maintenance, needing only occasional watering during prolonged dry spells. After flowering, cut back spent stems to the base, but avoid removing fresh shoots that will produce next year’s display. Apply a light mulch in spring to conserve moisture and tidy older foliage as needed.
