How fast do vinca grow?

Vinca, also known as periwinkle, typically grows at a moderate pace, reaching heights of about 12 to 18 inches within a single growing season. Under ideal conditions, such as well-drained soil and full to partial sun, they can spread rapidly, often covering large areas in a few years. Their growth rate can vary based on factors like climate, soil quality, and care provided. Regular watering and fertilization can enhance their growth and overall health.
