Periwinkle Seeds - Flower Plant for Home Gardens

Periwinkle seeds produce hardy plants with a low-growing, spreading to bushy growth habit and glossy green foliage. Depending on the variety, they may grow as annual bedding plants or perennial ground covers. Periwinkle performs best in full sun to partial shade with well-drained soil and moderate watering, showing good tolerance to heat and dry conditions once established. Suitable for garden beds, borders, containers, and ground cover, they establish quickly and provide continuous seasonal blooms.
