Euphorbia characias is an evergreen, shrubby spurge native to the Mediterranean Basin, prized for its architectural form and luminous spring display. Upright, woody stems rise 60–150 cm and carry narrow, blue‑green, glaucous leaves arranged in tight spirals, forming a dense, vase‑shaped clump. From late winter into late spring, towering terminal inflorescences open as chartreuse‑lime bracts with dark, often purplish nectar glands, creating a striking contrast that glows in low light and draws early pollinators. After flowering, those individual stems are best cut to the base, while new shoots from the crown sustain the plant’s evergreen presence. Exceptionally drought tolerant once established, it thrives in lean, fast‑draining soils and coastal or gravel gardens. The milky latex sap is irritant and toxic if ingested, so handle with gloves and site away from paths used by children and pets. Deer and rabbit resistant, it offers year‑round texture, pairs beautifully with grasses and silvery Mediterranean herbs, and performs reliably in full sun with minimal supplemental water.

How to care for Mediterranean spurge
Water
Water to establish during the first growing season, then water deeply but infrequently. Allow the top 5–8 cm of soil to dry completely between soakings. In Mediterranean or arid climates, mature plants often need only occasional summer irrigation; in cooler, wetter regions, supplemental water may be unnecessary. Avoid overhead watering in cool weather and never let the crown sit in winter‑wet conditions. Container specimens dry faster—check weekly in warm weather and ensure free‑draining potting mix.
Light
Full sun yields the most compact habit, strongest stems, and brightest chartreuse bracts. It tolerates light or open shade, especially in hotter inland climates where afternoon shade can prevent stress. Too much shade leads to lanky growth and flopping flower stems. Aim for 6+ hours of direct sun in mild climates, or morning sun with bright, filtered afternoon light where summers are intense. Avoid deep shade and sites with reflected heat without adequate soil moisture.
Nutrients
Feed sparingly. In the ground, incorporate a small amount of compost at planting, then apply a light top‑dressing of compost or a low‑rate, slow‑release balanced fertilizer (e.g., 5‑5‑5) once in early spring if growth appears weak. Avoid high‑nitrogen products that encourage lush, floppy stems and reduce flowering. Container plants may benefit from a diluted, balanced liquid feed at quarter‑strength monthly in spring through early summer. Always prioritize excellent drainage over fertility.
Temperature
Hardy in USDA Zones 7–10 (approx. 5–10°F/−15 to −12°C to 30–40°F/−1 to 4°C winters). Best in climates with dry summers and relatively dry, cool winters. Protect from prolonged, severe freezes and especially from cold, waterlogged soils. In marginal zones, site against a warm wall, provide winter drainage, and mulch the crown lightly (not smothering). Heat tolerant when soil is well‑drained; brief heatwaves are tolerated if roots are established and shaded by mulch.
