Vinca, a member of the Apocynaceae family, is a versatile plant with origins in Europe, particularly the Mediterranean region, where it grows naturally in the wild. This plant comes in both annual and perennial varieties, each with distinct characteristics. For clarity, perennial Vinca—commonly referred to as Periwinkle or Vinca Vine — is discussed separately. The annual varieties include Vinca minor and Vinca major. Annual Vinca, also known as flowering Vinca is available in both upright and trailing forms, producing abundant blooms throughout the Summer.

At Martin Garden Center, we offer both annual vinca in 4″ containers, 3″ containers and flats. From Spring till the end of June, we try to keep 3 full tables of upright annual vinca in flats or 3″ containers.

Growing and Caring for Vinca
Vinca are relatively adaptable and can thrive in various environments. They prefer well-drained soil rich in organic matter but can tolerate various soil types. Vinca is known for its ability to thrive in sunny locations with extreme heat, making it a preferred choice for Southern gardens. Most upright and trailing Vinca varieties can be propagated through seeds. However, purchasing young plants from nurseries or is a more common method. Specialty varieties can only be purchased by cuttings.
Annual vinca is relatively easy to grow as it blooms prolifically and can withstand drought. It is not commonly burdened by insects, but it does have a susceptibility to fungal problems. Botrytis blight, Alternaria leaf spot and root and stem rot can kill these plants when these plants are subjected to damp or soggy conditions. Space plants accordingly, only water when dry, and avoid overhead watering.
Leaves and Flowers
Vincas are known for their glossy, dark green leaves. The leaves grow in pairs along the trailing stems, providing an attractive backdrop for the vibrant flowers that bloom throughout the growing season. The flowers are typically five-petaled and star-shaped, coming in almost all shades except yellow. They possess a delicate beauty and are often adorned with contrasting centers. Vincas bloom from spring to first frost, providing a stable source of color in your garden.
Uses in Gardening & Landscaping
Trailing Vinca is a popular choice for container gardening, hanging baskets, and as a ground cover. The trailing habit of the trailing Vinca varieties lends itself well to cascading over the edges of pots or spilling over walls, creating a picturesque display.
The upright Vinca varieties will grow to heights from 8-12 inches and thus can make a great thriller in containers and will also quickly spread to cover the ground as a landscape plant. Their neat, bushy habit makes them perfect for creating borders along pathways or garden beds. The vibrant flowers add a splash of color that enhances the overall appeal. For a dramatic effect, plant them en masse in garden beds. Their continuous blooming throughout the season ensures a bright, attractive display.
