Madagascar Periwinkle

English Name

Catharanthus Roseus

Scientific Name

Description

Catharanthus Roseus is the only species that is ideal in the home. Sometimes it is confused with the genus Vinca. These plants create colour from Spring to early Autumn which are usually soft rose-pink, mauve, white and white with carmine-red center. They resemble the Busy Lizzie in appearance, but they are more difficult house-plants to grow.

Watering

Water plentifully, but do not allow the pot to stand in water.

Feeding

Once flowering has begun, feed every 2 weeks with standard liquid fertilizer.

Repotting

Move them in pots one size larger every 8 weeks until maximum size needed is 5 inch pot.

Germination

When the seeds have germinated, uncover the seed tray and begin watering the seedlings moderately enough to make compost moist, but allow top half-inch to dry out between waterings until they are about 1 inch high. Transfer each seedling into a 3 inch pot and treat as mature Catharanthus.

Propagation

Catharanthus can be propagated from tip cuttings as well as from seed. If propagated from seed it will flower more profusely. In late Winter or early Spring, take cuttings and sow seeds in shallow tray of moistened seed compost. Place tray in a plastic bag or propagator and stand in warm position and in bright filtered light.

Cultivation

Place plant indoors or outdoors in bright light but screen from intense direct sun. Bright light is essential for good flowering. Normal room temperatures are suitable at all times.

Tips

Catharanthus cannot tolerate temperature that fall below about 10 °C.

Care

Mist the foliage periodically. The plant is best grown as an annual. If you want to overwinter the plant, it is best to take cuttings in the Autumn.

Soil

House-plant compost.

The world's tallest-growing tree is the coast redwood (Sequoia sempervirens), which grows along the Pacific Coast of the United States, mainly in California. Interestingly enough, it's not the world's oldest-growing tree; that award goes to a bristlecone pine (Pinus aristata).
