Euphorbia milii (crown of thorns) is a spiny succulent shrub native to Madagascar, grown for its bright, long-lasting floral bracts and drought tolerance. It forms woody, thorn-covered stems with small, oval leaves clustered near the growing tips. The true flowers are tiny, surrounded by showy bracts in shades of red, pink, yellow, or white. The plant blooms over a long season in warm conditions and is widely cultivated in tropical and subtropical gardens, as well as in containers.

Thai Giant Hybrids are a group of Euphorbia milii cultivars selected in Thailand for exceptionally large floral bracts, often exceeding 2 in across, and a wide range of intense colors, including multicolored and patterned forms. These hybrids also tend to have more compact growth and heavier blooming compared to typical forms. Grow in full sun to light shade, in well-drained soil, and water moderately, allowing the soil to dry between waterings. Hardy in USDA Zones 10 11; protect from frost. Propagation is by stem cuttings, taken with care due to the plant s toxic latex sap.
