Catharanthus roseus hybrid Vinca Titan White ‘Polka Dot’ is a vigorous annual that dazzles with crisp white blooms marked by a bold red eye. In Cape Town’s Western Cape climate, it flowers continuously from late spring through autumn (October to May), thriving in the long, warm summers. Perfect for garden beds, borders, and patio containers, it delivers a cheerful carpet of colour with minimal effort. This sun-loving hybrid is heat and drought tolerant once established, making it ideal for coastal and water-wise gardens. Hardy, low-maintenance, and endlessly floriferous, it’s a reliable choice for instant seasonal impact. A true showstopper, Vinca Titan White ‘Polka Dot’ Catharanthus roseus hybrid brings brightness and resilience to every outdoor space. Use in garden beds or in containers for pops of colour.
Plant in well-drained soil and position in full sun for best flowering. Water regularly during establishment, then reduce as the plant becomes drought tolerant. Feed lightly with a balanced fertiliser every few weeks to encourage continuous blooms. Remove spent flowers to keep plants looking fresh and tidy. Protect from cold snaps, as vinca is frost-sensitive.
Although often called “Madagascar Periwinkle,” vinca hybrids like Titan White ‘Polka Dot’ are celebrated worldwide for their ability to flower non-stop in hot, sunny conditions where many other bedding plants struggle.
