    Euphorbia × martini 'Ascot Rainbow', commonly known as Martin's spurge, begins its life as a seed, germinating in favorable conditions of warmth and moisture in the spring. After germination, the seedling stage is marked by the emergence of the first leaves as the plant establishes a root system. As it enters the vegetative stage, the plant grows rapidly, producing multiple branches and leaves characteristic of the euphorbia family, showing variegated patterns of green, yellow, and pink. During the reproductive stage, typically in late spring to early summer, it develops tiny, inconspicuous flowers surrounded by showy, colorful bracts that attract pollinators. After pollination, the plant produces seeds, which are eventually dispersed to give rise to new plants, thereby completing the life cycle. Martin's spurge is perennial, so this cycle of vegetative growth and reproduction occurs annually, with the plant dying back to the ground in winter and resprouting from the rootstock in the spring.

      Early Spring

    • The most popular method of propagating Euphorbia × martini 'Ascot Rainbow', also known as Martin's Spurge, is through cuttings. This is usually done in the late spring or early summer when the plant is actively growing. Cuttings should be taken from healthy, disease-free plants, selecting semi-hardwood stems about 4 to 6 inches (10 to 15 centimeters) long. The lower leaves are removed, and the cut end is dipped in rooting hormone to encourage root development. The cuttings are then planted in a well-draining soil mix, kept moist, and placed in a warm spot with indirect light until roots have formed, which typically takes a few weeks. It's crucial to handle Euphorbia with care due to its milky sap, which can be an irritant to skin and eyes.
