Petrea White (Petrea volubilis 'White') is an ornamental tropical vine celebrated for its elegant appearance and prolific blooming.
Appearance: Petrea White features cascading clusters of pure white flowers, which are a striking contrast to the common purple varieties. The flowers are tubular and arranged in dense, pendant clusters that resemble garlands. The foliage is lush and green, providing a vibrant backdrop to the white blooms.
Growth Habit: This vine can grow vigorously, reaching lengths of 10-20 feet (3-6 meters). It is often used to cover trellises, fences, or walls, where it can create a dramatic floral display. The plant is evergreen in tropical and subtropical climates, maintaining its foliage year-round.
Climate: Best suited for warm, tropical to subtropical climates (USDA Hardiness Zones 10-11). It is not frost-tolerant and may need to be grown as an annual or container plant in cooler regions.
Light Requirements: Thrives in full sun to partial shade. For optimal flowering, it should receive at least 4-6 hours of direct sunlight daily.
Soil: Prefers well-drained soil with a slightly acidic to neutral pH.
Watering: Requires consistent moisture but should not be waterlogged. Water regularly, reducing frequency during cooler months or when the plant is not actively growing.
Fertilizing: Regular feeding with a balanced fertilizer during the growing season (spring and summer) promotes healthy growth and abundant blooms.
Pruning: Regular pruning helps control its growth and encourages more flowering. Prune after flowering to maintain shape and promote new growth.
Petrea White is valued for its showy blooms and is a striking addition to gardens and landscapes in suitable climates.
