The white flowering variety of Petrea volubilis, also known as Queen's wreath or sandpaper vine, shares most features with the more common purple variety. Its notable features include clusters of small, fragrant white flowers, textured leaves, and a vining growth habit. It's typically grown as a climbing vine and can reach impressive heights when given proper support. The white blooms add a touch of elegance to gardens or landscapes.
To care for a white flowering Petrea volubilis:
Light: Provide full sun to partial shade. It prefers bright, indirect light.
Water: Keep the soil consistently moist but not waterlogged, especially during the growing season. Allow the soil to dry out slightly between waterings.
Soil: Well-draining soil is essential. A mix of potting soil and perlite or sand works well for container-grown plants.
Temperature: Petrea volubilis prefers warm temperatures and can't tolerate frost. Keep it in a location where temperatures don't drop below 50°F (10°C).
Fertilizer: Feed with a balanced, water-soluble fertilizer every 4-6 weeks during the growing season (spring through fall).
Pruning: Prune regularly to control its size and shape. Remove dead or diseased branches and trim back excessive growth to encourage bushiness.
Support: Provide a sturdy trellis or support structure for the vine to climb. Train it as needed to encourage upward growth.
Pests and diseases: Monitor for pests like aphids, mealybugs, and scale insects. Treat promptly if any infestations occur. Additionally, watch for signs of fungal diseases and ensure good air circulation around the plant.
With proper care, your white Petrea volubilis should thrive and produce beautiful blooms.
