Honey-flowered spurge seeds (Euphorbia nicaeensis) succulent

Euphorbia nicaeensis — Nice Spurge or Honey-Flowered Spurge — is a bushy, mound-forming evergreen to semi-evergreen perennial with upright, red-flushed stems bearing oblong to lance-shaped, leathery, blue-green leaves. Terminal clusters of bright yellow-green flowers appear from spring to early summer, creating a striking architectural presence in the border or rock garden. Drought-tolerant once established. Hardy perennial.

⚠️ Toxicity warning: All parts of this plant are highly toxic if ingested. The milky sap may cause irritation to skin and eyes — wear gloves when handling.

Germination Guide

These seeds germinate irregularly over an extended period — patience is essential. Do not discard seed trays prematurely.

Temperature cycling for best results: Maintain constant moisture (not wet) at approximately +20°C [68°F] initially. Cold treatment below +5°C [41°F] is very effective at breaking dormancy. Alternatively, for a staged approach similar to Alstroemeria: sow and maintain at approximately +30°C [86°F] for 3 weeks, then move to +5°C [41°F] for 3 weeks, then grow on at +21°C [70°F].

Sowing: Cover seeds thinly. Do not place in direct sunlight during germination. Keep soil constantly moist throughout the germination period.
