The Periwinkle Plant | A Comprehensive Guide to Growing and Caring for Vinca Minor


Periwinkle plant, also known as Vinca minor or creeping myrtle, is a popular ground cover plant that is often grown for its beautiful flowers and easy maintenance. It is a low-growing, evergreen perennial that is native to Europe, but now grows in many parts of the world, including North America.

This plant is a great addition to any garden, as it requires very little care and is resistant to many common plant pests and diseases. It can also be used in a variety of ways, such as a ground cover, edging, or container plant.

In this blog, we will provide a full guide to growing and caring for periwinkle plant. We will cover its characteristics, ideal growing conditions, planting and propagation, care and maintenance, and common problems and solutions.


Periwinkle plant is a low-growing, trailing, evergreen plant that typically grows to a height of 4-6 inches (10-15 cm) and spreads up to 24 inches (60 cm) wide. It has glossy, dark green, ovate leaves that are 1-2 inches (2.5-5 cm) long and 0.5-1 inch (1-2.5 cm) wide. The leaves grow in pairs along the stem, and are arranged opposite each other.

The plant produces small, blue-violet, star-shaped flowers that bloom in early spring and continue to bloom sporadically throughout the summer. The flowers are about 1 inch (2.5 cm) in diameter and have five petals. Some varieties of periwinkle plant produce white or pink flowers as well.

Ideal Growing Conditions:

Periwinkle plant is a hardy plant that can grow in a wide range of growing conditions. However, it thrives in the following conditions:

  • Light: Periwinkle plant prefers partial shade to full shade. It can tolerate some sun, but too much sun can scorch its leaves and dry out the soil.

  • Soil: Periwinkle plant grows best in well-draining, moist, and fertile soil. It can tolerate a wide range of soil types, including sandy, loamy, and clay soils. However, it prefers slightly acidic soil with a pH between 6.0 and 7.5.

  • Water: Periwinkle plant requires regular watering, especially during the first year of growth. It can tolerate short periods of drought, but too much or too little water can cause its leaves to wilt or turn yellow.

  • Temperature: Periwinkle plant is a cold-hardy plant that can tolerate temperatures as low as -20°F (-29°C). It grows best in temperate climates, with average temperatures between 60°F and 80°F (16°C and 27°C).

Planting and Propagation:

Periwinkle plant can be propagated through seed or vegetative methods. Here are the steps to plant and propagate periwinkle plant:

  • Planting from Seed: Periwinkle plant can be grown from seed, but it takes a long time to grow and establish. The seeds should be sown in the fall, and the seedlings should be transplanted in the spring after the last frost. To sow the seeds, follow these steps:
  1. Prepare the soil by removing any weeds or debris and loosening the topsoil.
  2. Scatter the seeds on the soil surface and lightly press them into the soil.
  3. Water the soil thoroughly to moisten it, but avoid overwatering.
  4. Cover the area with a thin layer of mulch to retain moisture and protect the seeds from birds and other animals.
  5. Water the area regularly to keep the soil moist until the seedlings emerge.
  • Vegetative Propagation: Periwinkle plant is commonly propagated vegetatively by
taking stem cuttings or dividing established plants. Here are the steps to propagate periwinkle plant vegetatively:
  1. Stem cuttings: Take 3-4 inch (7-10 cm) long stem cuttings from the plant in early summer. Cut the stem just below a node, and remove the lower leaves. Dip the cut end in rooting hormone and plant the cutting in a pot filled with moist soil. Keep the soil moist and the cutting in a shaded area. After 4-6 weeks, the cutting should have rooted and can be transplanted to a permanent location.

  2. Division: Established periwinkle plants can be divided in early spring or fall. Dig up the plant and gently separate the roots into smaller clumps. Replant the clumps in a well-prepared soil, making sure the top of the root ball is level with the soil surface. Water the plants well after planting.

Care and Maintenance:

Periwinkle plant is a low-maintenance plant, but it still requires some care and maintenance to thrive. Here are some tips for caring for and maintaining periwinkle plant:

  • Watering: Periwinkle plant requires regular watering during its first year of growth. After that, it can tolerate short periods of drought. However, it is still important to water the plant regularly, especially during dry spells. Avoid overwatering, as this can cause the plant to rot.

  • Fertilizing: Periwinkle plant does not require much fertilizer. A light application of a balanced fertilizer in early spring can help promote healthy growth and blooming. Do not overfertilize, as this can cause the plant to become too leggy and produce fewer flowers.

  • Pruning: Periwinkle plant does not require much pruning. However, if the plant becomes too leggy or overgrown, it can be pruned in early spring or fall. Cut back the stems to 2-3 inches (5-7.5 cm) above the soil level. This will help promote new growth and prevent the plant from becoming too woody.

  • Mulching: Periwinkle plant benefits from a layer of mulch around its base. This helps retain moisture in the soil, prevent weeds from growing, and protect the plant's roots from extreme temperatures. Use a natural mulch, such as shredded bark or leaves, and apply a 2-3 inch (5-7.5 cm) layer around the plant.

Common Problems and Solutions:

Periwinkle plant is generally resistant to many common plant pests and diseases. However, it can still be affected by some issues. Here are some common problems and solutions:

  • Leaf Spot: Leaf spot is a fungal disease that causes circular brown or black spots on the leaves. To prevent leaf spot, avoid overwatering and overcrowding plants. Remove infected leaves and apply a fungicide if necessary.

  • Crown Rot: Crown rot is a fungal disease that causes the plant's crown to rot and the leaves to turn yellow or wilt. To prevent crown rot, avoid overwatering and plant the periwinkle in well-draining soil. Remove infected plants and do not replant in the same location.

  • Powdery Mildew: Powdery mildew is a fungal disease that causes a white or gray powdery coating on the leaves. To prevent powdery mildew, avoid overcrowding plants and provide good air circulation. Remove infected leaves and apply a fungicide if necessary.

  • Aphids: Aphids are small, soft-bodied insects that suck sap from the plant's leaves and stems. To prevent aphids, keep the plant healthy and well-watered. Remove infested leaves and use an insecticidal soap or spray to control the population.

  • Slugs and Snails: Slugs and snails 

are common pests that can feed on periwinkle plant leaves and stems. To prevent slugs and snails, keep the garden area clean and free of debris. Handpick the pests and dispose of them, or use a slug and snail bait to control the population.

  • Deer: Deer are known to feed on periwinkle plant leaves and flowers. To prevent deer damage, use physical barriers, such as fences or netting, to protect the plants. Alternatively, use deer repellents or plant deer-resistant varieties.


Periwinkle plant is not just a pretty ornamental plant; it also has several uses in traditional medicine and as a natural insecticide. Here are some of its uses:

  • Traditional Medicine: Periwinkle plant has been used in traditional medicine to treat a variety of ailments, including diabetes, high blood pressure, and memory loss. The plant contains alkaloids, such as vinblastine and vincristine, which have been used to treat certain types of cancer.

  • Natural Insecticide: Periwinkle plant contains alkaloids, which are toxic to insects. The plant can be used as a natural insecticide to control pest populations, such as aphids, whiteflies, and spider mites. To use, brew a strong tea using the plant's leaves and spray on affected plants.

  • Landscaping: Periwinkle plant is a popular landscaping plant, used for its attractive flowers and foliage. It is often planted as a groundcover in shady areas, where it can help control soil erosion and suppress weed growth.


Periwinkle plant is a versatile and attractive plant that can be used in a variety of ways. Whether you are looking for a low-maintenance ornamental plant, a natural insecticide, or a traditional medicinal herb, periwinkle plant has something to offer. By following the tips for planting, caring for, and maintaining periwinkle plant, you can enjoy its beauty and benefits for years to come.

    Won’t the mulch slow or even prevent the spreading of the clump? It seems the runners would prefer to root in soil rather than loose mulch. Thanks, Denny
