Periwinkle (Catharanthus Roseus American Pie Mix) - This upright Vinca ground cover plant is sure to attact attention during the entire growing season. It tolerates poor soil, drought and performs all summer with showy blooms.
Periwinkle flowers are suited to full sun areas or areas that get at least 6 hours of direct sunlight a day. Soil should be well drained and these drought tolerant plants do not need a lot of water so be careful not to overwater. No deadheading is needed to keep the outstanding display going!
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. Drought tolerant once established.
