How to Prune and Propagate Night Blooming Jasmine (Raat ki Rani) for More Flowers Night Blooming Jasmine ( Cestrum nocturnum ) is one of those plants that can transform an ordinary balcony into a fragrant evening garden. During warm weather, its small greenish-white flowers release a powerful fragrance after sunset. However, this fast-growing shrub can become difficult to manage in a container. You may have noticed long, thin branches spreading over the balcony railing, fewer flowers than expected, or a plant that produces plenty of green leaves but very few fragrant flower clusters. Sometimes, an older Raat ki Rani looks attractive for a few weeks during its flowering season and then becomes an untidy collection of long branches. Regular pruning can help solve these problems. It encourages branching, removes damaged growth and helps maintain a compact shape. Healthy branches removed during pruning can also be used to propagate new plants through stem cuttings....
Periwinkle Plant: Complete Growing, Care, Benefits, Flowers & Safety Guide 
Introduction to the Periwinkle Plant
The Periwinkle plant, widely known in India as Sadabahar, stands as one of the most reliable and visually appealing flowering plants for gardens, balconies, and landscapes. It is especially valued for its continuous blooming habit, low maintenance nature, and ability to thrive in warm climates. This plant, scientifically recognised as Catharanthus roseus, is often confused with other vinca species, making it essential to clearly understand its identity and characteristics.
We recognise the Periwinkle as a hardy ornamental plant that produces vibrant flowers in shades of pink, white, red, and purple, offering colour almost throughout the year in tropical and subtropical regions. Its adaptability and resilience make it a staple in Indian home gardens.
What Is the Periwinkle Plant?
Scientific Classification and Identity
The Periwinkle plant belongs to the Apocynaceae family and carries the botanical name Catharanthus roseus. It originates from Madagascar, yet it has naturalised extensively across India and other warm regions due to its adaptability.
Indian Names and Recognition
In India, the plant is commonly known as:
Sadabahar
Baramasi
These names reflect its year-round flowering nature, which is one of its most attractive features for gardeners.
Key Plant Characteristics
We observe the following essential traits:
Plant Type: Perennial herb or subshrub
Height: Typically 1–3 feet
Flowers: Five-petaled with a contrasting centre
Sunlight: Full sun to partial shade
Soil: Well-draining soil
Water Needs: Moderate

Periwinkle Flower: Beauty and Structure
Flower Appearance
The Periwinkle flower is simple yet elegant, featuring:
Five symmetrical petals
A distinct central eye
Smooth, rounded petal edges
Its minimalistic beauty makes it ideal for both formal landscapes and casual home gardens.
Flower Colour Variations
Periwinkle flowers are available in:
Pink (most common)
White
Red
Purple and violet shades
These colours create high visual contrast and enhance garden aesthetics.
Types of Periwinkle Plants
Madagascar Periwinkle (Catharanthus roseus)
This is the primary ornamental plant used in Indian gardens. It grows upright and bushy, producing abundant flowers.
Lesser Periwinkle (Vinca minor)
A different species that grows as a groundcover, spreading horizontally and forming dense mats.
Understanding “Vinca”
The term Vinca is often used loosely, but it refers to multiple species, not just one plant. This distinction is critical for accurate gardening practices.
Periwinkle vs Vinca Minor: Key Differences
| Feature | Madagascar Periwinkle | Vinca Minor |
|---|---|---|
| Scientific Name | Catharanthus roseus | Vinca minor |
| Growth | Upright | Trailing |
| Flowers | Multi-colored | Mostly blue-violet |
| Usage | Ornamental flowering plant | Groundcover |
| Climate | Warm regions | Temperate zones |
Understanding this difference prevents planting mistakes and ensures proper care.
How to Grow Periwinkle Successfully
Ideal Growing Conditions
We ensure optimal growth by focusing on:
Full sunlight exposure
Good air circulation
Well-draining soil
Avoidance of waterlogging
Does Periwinkle Need Full Sun?
Yes, full sun promotes maximum flowering. Partial shade is acceptable, but too much shade results in weak growth and fewer flowers.
Best Soil Requirements
Loose, well-drained soil
Addition of organic compost
Avoid heavy clay soils.
How to Plant Periwinkle
To plant periwinkle (Vinca) successfully in garden beds, we follow a simple and effective method that ensures strong growth and continuous flowering. First, we choose a sunny to partially shaded location, as this plant blooms best with good light. Next, we prepare loose, well-draining soil by mixing garden soil with compost and a little sand for better aeration. We then dig a hole slightly wider than the root ball to allow easy root spread. The plant is placed at the same depth as in the nursery pot, ensuring the crown is not buried too deep. After positioning, we gently fill the soil around the roots and press lightly to remove air pockets. We water thoroughly immediately after planting to help the roots settle. Proper spacing of about 20–30 cm between plants is maintained to promote airflow and prevent diseases. With this approach, periwinkle establishes quickly and produces healthy foliage and vibrant blooms with minimal maintenance throughout the season.
Planting in Garden Beds
We follow a structured approach:
Select a sunny location.
Prepare loose soil
Dig an appropriate hole.
Place the plant at the proper depth.
Water thoroughly
Maintain spacing for airflow.
Growing Periwinkle in Pots
Use medium-sized pots
Ensure drainage holes
Use light potting mix.
Place in bright sunlight
Water moderately
Periwinkle Plant Care Guide
Watering
Keep soil slightly moist, not soggy.
Reduce watering during rainy seasons.
Avoid overwatering to prevent root rot.
Fertilizing
Apply balanced fertiliser occasionally.
Avoid excessive feeding
Focus on maintaining flowering balance.
Pruning and Maintenance
Remove damaged stems
Trim for bushy growth
Maintain shape regularly
Periwinkle Plant Lifespan
The lifespan depends on:
Climate
Soil conditions
Care practices
In warm regions like India, Periwinkle behaves as a long-lasting perennial, while in colder climates it may be treated as an annual plant.
Is Periwinkle an Indoor Plant?
Periwinkle is primarily an outdoor plant. While it can survive indoors temporarily, it requires:
Strong sunlight
Good airflow
Indoor flowering is usually limited without sufficient light.
How to Propagate Periwinkle
