Garden Plant Seed Flower Seed Periwinkle Vinca Rosea Dwarf 100 Mixed Seeds - Catharanthus Roseus

Grow Vinca seeds indoors 6 - 10 weeks before the last frost is expected. Cover the Periwinkle seeds with 1/4 inch of potting mix, spray with water to moisten and press down lightly. Vinca flower 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. The plants can be moved outside once the temperature is consistently above 65F degrees.
