Description:

  • Poinsettia ‘Rose and White’ is a cultivar of Euphorbia pulcherrima known for its striking bracts in shades of pink and white.
  • Bracts are modified leaves that resemble petals and surround the inconspicuous true flowers.
  • Typically grows as a small shrub, reaching a height of 0.6 to 4 meters.
  • Leaves are green, often tinged with red or purple at the edges.
  • The cyathia, or flower structures, are small and yellow and found within the center of the colorful bracts.

Known Range:

  • Native to Mexico and Central America.
  • Cultivated worldwide as an ornamental plant, especially during the Christmas season.

Care Requirements:

  • Light: Requires bright, indirect light. Avoid direct sunlight, as it may scorch the leaves.
  • Temperature: Thrives in temperatures between 65-75°F (18-24°C) during the day and slightly cooler at night.
  • Watering: Allow the soil to dry slightly between waterings, but do not let it completely dry out. Overwatering can lead to root rot.
  • Humidity: Prefers moderate to high humidity levels. Mist the plant regularly, especially during dry indoor conditions.
  • Soil: Well-draining soil is essential to prevent waterlogging.
  • Fertilization: Feed with a balanced, water-soluble fertilizer every 2-4 weeks during the growing season (spring and summer).
  • Pruning: Prune after flowering to maintain a bushy shape. Wear gloves, as the milky sap may irritate skin.
  • Propagation: Can be propagated from stem cuttings taken in spring or early summer. Dip cuttings in rooting hormone and plant in a well-draining potting mix.
  • Pests and Diseases: Susceptible to aphids, whiteflies, and fungal diseases. Keep an eye out for signs of infestation or disease and treat promptly.
