40+ This Periwinkle has gorgeous, 2 inch blooms that are bold and stand out beautifully in the garden as a ground cover plant or in a basket or pot. Start Periwinkle seeds for a low-growing yet vigorous spreading annual. Vinca Periwinkle is exceptionally low-maintenance! It takes the heat, does well with poor soil, and doesn't even need deadheading to bloom continuously. Grow Vinca ground cover seeds indoors 4 - 6 weeks before the last frost is expected. Cover the seeds with 1/4 inch of potting mix, spray with water to moisten and press down lightly. Periwinkle ground cover seeds will not germinate in any sort of light, so cover trays or containers with a black plastic sheet or a newspaper. Lift the plastic or newspaper regularly to moisten by misting. Once Periwinkle seedlings emerge, they need bright light. At about 2 - 3 inches tall, transplant the strongest plants into individual pots. Periwinkles can be moved outside once the temperature is consistently above 65F degrees. Directly sowing Periwinkle seeds is not recommended, but if you choose to direct sow, follow the same steps as above. Wait until danger of frost has passed and temperatures are consistently warm, and prepare the soil well so that it is light and fine. Water Vinca Periwinkle regularly to get it established, but once it is established, it is very drought tolerant. Periwinkle ground clover plants readily re-seed themselves. Will bloom summer through fall.
