Vinca, commonly known as periwinkle or myrtle, is a versatile plant species that belongs to the Apocynaceae family. Its origins can be traced back to Europe, particularly the Mediterranean region, where it thrives in the wild. Vinca is well-loved for its evergreen foliage, adorned with glossy, lance-shaped leaves. It also has attractive, five-petaled flowers that come in shades of pink, purple, or white.
Growing and Caring for Vinca
Vincas 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 grow in both sunny and shady locations, making it a versatile choice for different areas in the garden. However, it tends to perform best in partial shade or filtered sunlight, as excessive heat and direct sun can cause the leaves to scorch.
Vincas can be propagated through seeds, cuttings, or division. Starting from seeds is time-consuming, as they require stratification (a period of cold treatment) before germination. However, purchasing young plants from nurseries or taking cuttings from established plants are more common methods.
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 trumpet-shaped, coming in shades of lavender, purple, blue, or white. They possess a delicate beauty and are often adorned with contrasting centers. Vincas bloom from spring to fall, providing a stable source of color in your garden.
Uses in Gardening & Landscaping
Vinca is a popular choice for container gardening, hanging baskets, and as a ground cover. Its trailing habit lends itself well to cascading over the edges of pots or spilling over walls, creating a picturesque display. It can effectively outcompete weeds, reducing the need for excessive maintenance. Its flowers also make lovely additions to cut flower arrangements, which can last several days in a vase. Vinca is often combined with other shade-loving plants to create colorful and dynamic displays. It can also be used as a ground cover, especially in shady areas where other plants may not thrive.
Vinca Minor
One of the most popular species is Vinca minor, known as common periwinkle or creeping myrtle. This plant is a low-growing, spreading ground cover and is often used to control slope erosion and fill in gaps in the garden. It has small, blue-purple flowers that appear in early spring and can continue to bloom intermittently throughout the growing season.
Do Deer Eat Vinca?
Deer typically avoid eating Vinca, commonly known as periwinkle or Madagascar periwinkle. Vinca is deer-resistant due to the bitter taste and toxicity of its foliage. The plant contains alkaloids that can be harmful if ingested, and deer tend to avoid plants with such characteristics.
Is Vinca Perennial or Annual?
Vinca is typically grown as an annual in most regions, including the Upstate, because it is sensitive to freezing temperatures and does not survive winter (often).
Is Vinca Poisonous To Dogs?
Yes, Vinca is considered toxic to humans and pets, including cats and dogs. Vinca contains alkaloids, specifically vinca alkaloids, which can be harmful if ingested. Ingestion of Vinca may lead to vomiting, diarrhea, abdominal pain, and other signs of gastrointestinal distress.
