Very fast. Annual vinca seedlings will reach full-size by mid-summer.
What plants pair well with annual periwinkle?
Plants that complement annual periwinkle enhance the striking eye of the vinca flower.

Additionally, other heat and sun-loving plants that work well with vinca include moss rose and penta flowers.
How should you use it in your garden?
Utilize the rapid growth habit of annual vinca to enhance your garden. Purchase a six-pack of vinca plants to fill any empty sunny areas in your garden border where your perennials are still growing.
