Vinca, also known as periwinkle, is a flowering perennial. The plant has glossy evergreen leaves, blue-lavender flowers and a trailing vine habit. Because the plant is a low grower and reaches a height of 6 inches, it is often used as a ground cover in flower beds or to fill in bare spaces in the flower garden. Vinca can also be planted outside of flower beds and will grow nicely in the lawn when planted beneath trees or shrubs.
Choose a location to plant your vinca. The plant can tolerate both sunny and shady locations. However, flowering will be reduced in very shady areas and locations that receive full sun all day should be avoided because your plant will lose some of its vigor. The best locations are ones that receive partial sun and shade throughout the day.
Use a garden trowel to dig small holes that are 10 to 12 inches apart. The holes should be dug to the same depth as the vinca growing containers. The spacing between holes will enable the plants to spread and eventually come together. If you want the plants to have a thick, carpet effect, reduce the spacing of your holes to 4 to 6 inches.
Place the plants into the holes and backfill the original soil into the holes. Gently tamp down on the soil around the plants to ensure no air pockets remain around the roots of the plants.
Water the plants and cover with a thin layer of mulch. You should plan to water the plants every few days if your area experiences a dry spell. If your area receives 1 inch of rain per week, do not water. The goal is to keep the top inch of soil slightly moist, not wet, at all times.
Plan to fertilize your vinca each spring with a water soluble plant food.
