Periwinkle (Catharanthus Roseus Titan Mix Bubble Gum) - Titan Bubble Gum periwinkle flower seed mixture blooms up to two weeks faster than most other vinca varieties.  It has excellent branching and big, vibrant flowers.  Periwinkle has very low watering needs and is outstanding in sunny, hot and dry conditions.  Titan vinca will also grow in light shade.  Reaching, 14 - 16 inches in height and only 10 - 12 inches wide, a very good variety for containers, beds, and borders.

Vinca is best grown in 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.  Season long blooms bursting with color from late Spring to late Summer for gardens and containers.

Grow Vinca seeds indoors 4 - 6 weeks before the last frost is expected. Cover the Vinca 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. Directly sowing 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.
