WaterMadagascar periwinkle, or 'Pretty in Pink', prefers to be watered regularly but allow the top inch of soil to dry out before watering again. Typically, this may mean watering every 5 to 7 days, depending on the climate conditions and time of year. Use room temperature water and gently water the plant until the excess drains out the bottom; this might equate to around 16 to 32 ounces for a medium-sized pot every week. Over-watering can lead to root rot, so it's essential to ensure good drainage and not to let the plant sit in water.
LightMadagascar periwinkle thrives best in bright, indirect light but can also tolerate direct sunlight. However, in very hot climates, the plant should be protected from the harsh afternoon sun. A south-facing window with some light shading is ideal, ensuring the plant receives a few hours of sunlight daily without being exposed to hot midday rays.
TemperatureThe ideal temperature range for Madagascar periwinkle is between 65 and 85 degrees Fahrenheit. It can survive minimum temperatures of around 60 degrees Fahrenheit at night and should not be exposed to temperatures below 50 degrees Fahrenheit, as cold can damage the plant. This warmth-loving perennial favors consistently warm conditions without drastic temperature changes.
PruningPruning Madagascar periwinkle helps to maintain its shape and encourage bushier growth. Prune the plant lightly throughout the growing season to remove any dead or yellowing leaves and spent blooms. A more severe pruning can be done in early spring, cutting back up to one-third of the plant to stimulate new growth and flowering. Pruning is best done with clean, sharp shears to prevent damage to the stems.
CleaningAs needed
SoilMadagascar Periwinkle thrives in well-drained soil with a pH between 6.0 and 7.5. A mix containing loamy or sandy soil, enriched with organic matter like compost or peat, is ideal. Due to its tolerance for poor soils, it can grow in a range of conditions but prefers moderately fertile substrates.
RepottingMadagascar Periwinkle should be repotted every 2-3 years to prevent root crowding and replenish nutrients in the soil. Young plants may require more frequent repotting as they establish and grow.
Humidity & MistingMadagascar Periwinkle prefers moderate humidity but is quite adaptable. The ideal humidity level for this plant ranges from 40% to 60%, although it can tolerate lower levels without issue.
Suitable locationsIndoor
Place in bright, indirect light and water when soil feels dry.
Outdoor
Plant in full sun to partial shade and well-draining soil.

Life cycleCatharanthus roseus (Albus Group) 'Pretty in Pink', commonly known as the Madagascar periwinkle, begins life as a seed which germinates in warm soil with temperatures around 75-80°F (24-27°C). Once germination occurs, the seedling emerges with its first pair of true leaves and begins its vegetative growth phase, during which it develops a sturdy stem and a robust leaf system. As it matures, the plant enters the flowering stage, producing distinctive pink flowers that are capable of self-pollination or can be pollinated by insects, leading to seed production. After pollination, the plant develops a dry fruit capsule containing seeds that are dispersed by wind or other means. In tropical and subtropical climates, the Madagascar periwinkle may continue to grow and repeat the flowering and seeding cycle year-round; however, in temperate zones, it is treated as an annual plant and completes its life cycle within one growing season. As the growing season ends or when temperatures drop, the plant will die, leaving behind seeds to begin the cycle anew if conditions are favorable.
PropogationPropogation time
Spring to Summer
Propogation: The most popular method of propagation for Catharanthus roseus, or the Periwinkle 'Pretty in Pink', is through seed sowing. The ideal time to start seed propagation is in late winter to early spring, to allow time for the plants to mature before the warm summer months. To propagate by seeds, first, obtain a high-quality seed-starting medium and fill seed trays or small pots. Sprinkle the fine seeds over the moistened soil and lightly press them in, but do not cover them as they require light for germination. Place the tray in a warm location, ideally between 75 to 80 degrees Fahrenheit (24 to 27 degrees Celsius), and maintain constant moisture without overwatering. Germination usually occurs within 10 to 14 days. Once the seedlings have grown sufficiently and the risk of frost has passed, they can be transplanted outdoors to their final growing location.
