Must Know Plant Care Tips: In climates with mild winters, periwinkle can become invasive. However, unwanted plants pull out easily, making them fairly easy to maintain. If left to its own devices, however, it will spread indefinitely. Cutting the plants back will encourage brighter, more colorful growth. Humus-rich soil is best.
Plant Problem Solver: If you have a shady spot where grass dies out and most perennials won’t grow, consider periwinkle. It’s pretty tough and can make a great ground cover. It is also resistant to deer and makes good slope and erosion control. It attracts birds and works well in containers, where it will obviously not be able to send shoots into unwanted areas. Its rigorous growth can help keep weeds out of areas where you don’t mind a ground cover, but don’t want to be pulling ugly weeds.
Pretty Pairings: Try planting periwinkle next to hakone grass, lungwort, and lilyturf.
