ABOUT

This plant, commonly known as Mrs. Robb's Bonnet, is a perennial with an attractive appearance that can add a lush green touch to gardens. It possesses vibrant green leaves that are shaped somewhat like a spade found in playing cards, with a slightly rounded form. The foliage is typically evergreen, providing year-round color in milder climates. During its blooming season, which generally occurs in the spring, Mrs. Robb's Bonnet produces small flowers that can be described as lacking prominent petals but surrounded by bright yellow-green bracts. These bracts are the showy part of the flower and can light up a shady garden spot with their cheerful hue. The flowering stems rise above the foliage, and due to their unique structure, the blooms form an eye-catching contrast against the darker tones of the leaves. The overall effect of the plant is one of robustness with a spreading habit, gracefully occupying space in the garden and providing a lush ground cover. While the plant can be appreciated for its resilience and decorative qualities, care should be taken since it is known to contain a sap that can be irritating to skin and harmful if ingested.

Pruning
  • water dropWater

    Wood Spurge should be watered thoroughly whenever the top inch of soil feels dry to the touch, typically every week during active growth in spring and summer months. In the winter, you should reduce watering to every two to three weeks or whenever the soil is dry, as the plant's water requirements decrease. Make sure to water the plant at the base to avoid wetting the foliage, using gallons of water that will saturate the soil without leaving it soggy. Wood Spurge appreciates consistent moisture but is somewhat drought-tolerant once established. It's important to provide about one gallon of water for an outdoor plant to ensure it's well-hydrated.

  • sunLight

    Wood Spurge thrives in partial shade but can also accommodate full sun to full shade conditions. The ideal spot for Wood Spurge is under the dappled light of a tree canopy or in a bright but shaded garden area. Avoid intense afternoon sun in hotter climates as it can scorch the leaves.

  • thermometerTemperature

    Wood Spurge performs best in a temperature range between 60°F and 75°F but can tolerate temperatures as low as 50°F and as high as 80°F. It is hardy and can survive winter temperatures down to about -10°F for short periods, which suggests it can be left outdoors year-round in many climates.

  • scissorsPruning

    Prune Wood Spurge in late winter or early spring to remove any dead or damaged parts of the plant and to maintain its shape. Pruning back hard after blooming can also rejuvenate the plant and encourage bushier growth. It isn't usually necessary to prune Wood Spurge frequently unless it becomes too large for the space it occupies.

  • circleLife cycle

    Euphorbia amygdaloides var. robbiae, commonly known as wood spurge, begins its life cycle as a seed, often dispersed by explosive dehiscence where the capsule bursts open, flinging the seeds some distance away. Upon finding a suitable moist and shaded environment, the seed germinates, typically in the spring. After germination, the seedling develops into a juvenile plant, growing a deep root system and basal rosette of leaves, ready for photosynthesis. As the plant matures, it forms upright stems with whorls of dark green leaves and eventually produces its characteristic greenish-yellow flowers, often mistaken for petals but are actually modified leaves called bracts, blooming from early to mid-spring. Following pollination by insects, the plant sets seed again, continuing its reproductive cycle. Throughout its life, wood spurge will also propagate vegetatively through underground runners, forming dense colonies that can outcompete other vegetation.

  • sproutPropogation

    • Propogation time

      Spring to early summer

    • Propogation: The most popular method of propagating Euphorbia amygdaloides var. robbiae, commonly known as Wood Spurge, is by division. The best time to divide the plant is in early spring or fall. To propagate by division, carefully dig up the plant, ensuring a large root mass is intact. Using a sharp shovel or knife, divide the root clump into smaller sections, each having several shoots and a portion of the root system. Replant the divisions at the same soil level as they were originally growing, and space them about 12 to 18 inches (approximately 30 to 45 centimeters) apart. Water the new divisions thoroughly to help establish them. This method encourages quick and effective propagation, allowing gardeners to spread the beauty of Wood Spurge throughout their landscape.
