Days to Germination:10-21 days
Euphorbia marginata, Snow on the Mountain. Start transplants indoors 6 to 8 weeks before setting out after the last frost date. Sow seeds in sterile seed starter mix. Pamper with 70°F temperatures, good air circulation, strong light and even moisture. Cover with plastic wrap until sprouts emerge: then discard plastic. Harden off seedlings by gradually acclimating them to the outdoors for 1 to 2 weeks. Carefully transplant out into rich, well-draining soil in full sunlight spaced 8" to 12" apart. In warmer climates, direct sow after the threat of frost has passed. Prized for its top-branching white and green variegated foliage, Euphorbia’s milky juice is toxic and is a skin and eye irritant. Cut flower ends should be flame seared or dipped in boiling water. Summer leafing. Height: 12".
