Vinca major (Bigleaf Periwinkle)

It's native to the Mediterranean and is grown in USDA Zones 7-9. This low-growing plant is one of the most popular perennials for the garden; it offers a dark green 'carpet' of foliage and a profusion of star-shaped, lavender, blue and purple flowers. While it is a good groundcover, it can also become invasive, so it needs to be pruned and controlled in order to keep it in its place.

Grow Vinca major in soil that has good drainage, and provide it with regular water. In the summertime, a little extra water can help the plant to survive through the heat. As winter arrives, water needs to be reduced and the soil should be allowed to dry out between waterings. The mature plant is cold hardy, although protection from frost is recommended to keep this plant from damage.

When growing Vinca major in pots, be sure to use a pot that is big enough for the plant root system. Provide plenty of drainage and water regularly, allowing the soil to dry out in between waterings. If you live in a particularly cold region, the plant should be kept in a sheltered environment, or even brought indoors during the winter months.

Overall, Vinca major is a popular and hardy groundcover, which offers a plethora of lavender, blue and purple star shaped flowers and a mass of dark green foliage - as long as it is pruned and controlled. Providing regular water and a little extra protection in cold regions and winter months will keep your plant thriving year-round.
