Madagascar Periwinkle (Catharanthus roseus 'Cooler Strawberry Vinca') - Description
A bushy, green bedding plant with 1"-3" wide blooms in pure pink. Usually grows 1'-2' tall and wide. Mediterranean and carpet varieties tend to be shorter and wider and make good ground covering, whereas the Pacific and Cooler varieties grow in round, compact formations. These are perfect for long lasting flower power along with a low maintenance schedule!
Madagascar Periwinkle (Catharanthus roseus 'Cooler Strawberry Vinca') - Blooming
Blooms all summer and generally will keep their flowers after other summer flowers are spent, as late as mid-November, even in areas with regular autumn frost.
Madagascar Periwinkle (Catharanthus roseus 'Cooler Strawberry Vinca') - Growth
Madagascar Periwinkles, although perennials, are generally grown as annuals. They do well with full sun or partial shade. Can survive most winters, but may look rather ragged.
Madagascar Periwinkle (Catharanthus roseus 'Cooler Strawberry Vinca') - Planting
Freely self-sows. To get flowers on the first year, sow seeds indoors in winter. Enjoys warm and hot temperatures, but newer strains have recently been created to withstand lower temperatures. Ideally, soil should be disease-free and have a pH between 5.5 and 5.8. Expect germination in about 4 to 6 days. Frequently, potted plant varieties are available at nurseries in late spring.
Madagascar Periwinkle (Catharanthus roseus 'Cooler Strawberry Vinca') - Pest
Undue stress, high soil pH and low temperatures can foster Thelaviopsis (black root rot), which can cause leaf damage, loss of root hairs, yellowing, stagnated plant growth and even plant death. Any infected plant should be removed from the vicinity of other plants to avoid the spread of the disease. Aphids, thrips, rhizoctonia and pythium are also potential threats.

Madagascar Periwinkles are herbaceous perennial plants native to Madagascar and India. Although the sap is poisonous if ingested, extracts have been used for hundreds of years in herbal medicine in Madagascar for the treatment of diabetes, as hemostatics and tranquilizers, to lower blood pressure, and as disinfectants. The extracts are not without their side effects, however, which include hair loss. Frequently used as a bedding plant in gardens.
