10 Pelleted Seeds Polka Dot Vinca Catharanthus roseus Annual Flower

Polka Dot Vinca, also known as Catharanthus roseus, is a warm-season annual prized for its glossy green foliage and cheerful, rounded blooms that appear in soft shades of pink, rose, and white. Plants form tidy, compact mounds that perform reliably through heat and humidity, making them a favorite for borders, containers, and mass plantings where season-long color is desired.

These pelleted seeds are coated for easier handling and more even sowing, which helps when starting indoors or direct sowing into prepared beds. The plants work well in mixed patio pots, hanging baskets, and front-of-border positions, where their steady bloom and clean habit provide dependable ornamental value from summer into early fall. They pair nicely with trailing annuals and fine-textured foliage plants.
