Spurge Euphorbia × pasteurii
ABOUT
Euphorbia × pasteurii, commonly known as spurge, is a hybrid perennial plant with a distinctive appearance. This plant showcases a beautiful mounding habit with evergreen foliage that remains attractive throughout the year. The leaves of spurge are narrow, elongated, and arranged in a spiral fashion around the stems. They boast a rich, dark green color that can sometimes take on a reddish or purplish hue during the cooler months or in response to stress. Spurge is well-known for its striking flowers, which aren't true flowers in the traditional sense. Instead, what appears to be a single flower is a specialized structure called a cyathium, which contains several tiny male flowers and a single female flower. The cyathia are clustered together within cup-shaped bracts that are often a bright, eye-catching yellow-green or chartreuse color, creating a showy display that looks fantastic against the dark foliage. These bracts can sometimes be mistaken for petals because of their vivid coloration and prominence. The stems of spurge are sturdy, and the overall form of the plant is quite tidy and dense, which makes it an excellent choice for borders, rock gardens, or as a structural element in mixed plantings. It provides a strong visual impact with its contrasting foliage and floral structures. Despite its ornamental qualities, one should handle the plant carefully as it produces a milky sap that can be irritating to the skin and toxic if ingested. Overall, spurge adds a unique texture and color contrast to gardens and landscapes.

WaterEuphorbia × pasteurii, commonly known as Spurge, should be watered thoroughly, allowing the soil to dry out between waterings to prevent root rot. Typically, watering once a week during the growing season is sufficient. During the winter, reduce watering to every other week or less, depending on the humidity and temperature of your environment. It's essential to provide about one gallon of water to the soil around the plant, ensuring even moisture distribution without waterlogging the soil.
LightSpurge thrives best in full sun to partial shade environments. Ideally, it should receive at least six hours of sunlight daily, while being protected from the intense afternoon sun, especially in hotter climates. A spot that offers morning sunlight with dappled afternoon shade would be optimal for this plant.
TemperatureSpurge prefers temperatures between 50°F and 75°F and should not be subjected to temperatures below 30°F as it can cause damage to the plant. While it can tolerate a brief frost, prolonged exposure to cold will harm it. The ideal temperature range allows it to flourish and should be maintained as much as possible throughout the year.
PruningPruning Spurge is generally done to remove spent flowers, promote bushier growth, or maintain desired shape and size. It's best to prune in late winter or early spring, before new growth begins. Pruning can be carried out annually or as needed to remove any damaged or overgrown branches.
CleaningAs needed
SoilEuphorbia × pasteurii, commonly known as Spurge, thrives best in a well-draining soil mix with equal parts of loam, sand, and peat to ensure good drainage and aeration. Ideal soil pH for Spurge is between 6.0 to 7.5. A balanced slow-release fertilizer can be added to the mix for optimal growth.
RepottingEuphorbia × pasteurii, or Spurge, generally requires repotting every 2 to 3 years to replenish nutrients and to accommodate root growth. Choose a pot only slightly larger than the previous one to prevent waterlogging due to excess soil.
Humidity & MistingEuphorbia × pasteurii, known as Spurge, fares well in typical indoor humidity levels, which range from about 40% to 60%. The plant does not require high humidity and can tolerate drier air without adverse effects.
Suitable locationsIndoor
Place Spurge in bright, indirect light indoors.
Outdoor
Plant Spurge in full sun to part shade outdoors.

Life cycleEuphorbia × pasteurii, commonly known as spurge, begins its life as a seed, which germinates in warm, moist soil where it forms a small root system and a shoot that emerges above the ground. As a seedling, it develops into a young plant with characteristic leaves and starts photosynthesizing to fuel its growth. Once mature, the spurge produces small, inconspicuous flowers typically encased within bracts, growing in clusters called cyathia, where pollination occurs and seeds are produced. After pollination, seeds develop and are eventually dispersed by various mechanisms, including wind or animals. The plant reaches maturity, often forming bushy clumps and continues to grow and spread, repeating the flowering and seeding cycle annually. At the end of its life span, which can vary in length but typically lasts several years, the plant will eventually senesce and die, leaving seeds to continue the species' lifecycle.
PropogationPropogation time
Spring to Summer
Propogation: Euphorbia × pasteurii, commonly known as Spurge, is primarily propagated through the division of its rootball. The best time to perform this propagation method is typically in the spring, just as the plant begins to show new growth. To propagate by division, carefully lift the entire plant from the ground, ensuring to retrieve as much of the root system as possible. Once out of the soil, use a sharp spade or knife to divide the rootball into sections, each with several growth points. Replant the divisions at the same depth they were originally growing, and water them thoroughly to help establish the new plants. It's crucial to handle all parts of the plant with caution and wear gloves, as the sap can be an irritant to the skin and eyes.
