Are Vinca Easy to Grow from Seed?

Yes, Vinca (also known as Catharanthus roseus) is one of the easiest annuals to grow from seed. 

Start your Vinca seeds indoors 10-12 weeks before your last frost date. Use our Bio Dome to maintain the right moisture and space for your seedlings.

Once established, they’re very low maintenance. Just give them sunshine and occasional watering. Be sure to transplant after the soil warms up.

Are Vinca and Periwinkle the Same Thing?

Vinca and periwinkle are often used interchangeably, but technically, no, "vinca" refers to the annual flowering plant Catharanthus roseus, while "periwinkle" can also refer to the ground cover Vinca minor, a perennial.

If you're planting for summer color, you're most likely looking for annual vinca.

Do Vinca Like Full Sun or Shade?

Vinca loves full sun. These heat-resistant flowers do best when they get at least 6 hours of sunlight each day.

While they can handle some afternoon shade, full sun brings out the brightest colors and longest bloom time.

Which Companion Plants Pairs Well With Vinca?

5 Steps to Plant Your Vinca Seeds

Planting vinca from seed is simple, but following a few key steps can help you get the best results. Here's how to start strong:

  1. Start seeds indoors 10–12 weeks before your region’s last frost.

  2. Use a quality seed-starting mix and gently press seeds into the surface.

  3. Keep soil moist and warm (about 75°F) until germination.

  4. Once seedlings have 2-3 sets of leaves, transplant them into bigger containers.

  5. Move outdoors after the soil warms and night temps stay above 60°F.

With just a bit of prep, you’ll enjoy a season full of bright vinca blooms in your garden.
