Description
Vinca (Catharanthus roseus), also known as Periwinkle or Madagascar Periwinkle, is a hardy, heat-loving annual (or perennial in warmer climates) that produces a profusion of colorful, star-shaped blooms throughout the summer. Native to Madagascar, Vinca is popular for its ability to thrive in hot, sunny conditions with minimal water, making it ideal for low-maintenance gardens, borders, and containers. The flowers come in shades of pink, white, red, lavender, and purple, often with a contrasting eye in the center, adding a lively touch to the landscape.
Vinca typically grows 12 to 18 inches tall and wide, forming a dense, bushy mound that makes it an excellent ground cover or bedding plant. This plant thrives in USDA zones 9-11 as a perennial but is grown as an annual in most other regions. It performs best in full sun but can tolerate partial shade, and it requires well-draining soil to prevent root rot. Highly drought-tolerant once established, Vinca needs little water, making it perfect for xeriscape gardens and hot, dry locations where other plants may struggle.
Low-maintenance and pest-resistant, Vinca requires no deadheading, as the flowers naturally drop after blooming, keeping the plant tidy. It is also deer-resistant, adding to its appeal in various garden settings. With its vibrant blooms, resilience in hot weather, and easy-care nature, Vinca is a versatile choice for gardeners looking to add season-long color and texture to sunny spots with minimal effort. Its tolerance to challenging conditions makes it a reliable choice for both formal and casual garden designs.
