Vinca, commonly known as Sada Bahar (سدا بہار), brings lasting colour to sunny pots, borders, rooftop planters and flower beds during Pakistan’s warmer months. Its tidy green foliage forms a neat background for flowers in red, pink, purple, white and other vibrant shades.
Gardeners can choose a colourful mix for an informal display or individual F1 colours for a coordinated planting. The collection includes classic solid colours, contrasting halo centres and patterned flowers for different garden styles.

Vinca Mix combines several flower colours in one packet, making it suitable for mixed pots, long planters and colourful flower beds.
Individual F1 varieties are useful when planning a particular colour scheme. Deep Orchid and Purple add rich tones, while Punch, Cranberry and red varieties create a brighter display.
Halo varieties produce flowers with a contrasting centre. These work well along pathways and at the front of flower beds, where the flower pattern can be seen clearly.
Polka Dot adds a distinctive bicolour appearance. It can be planted by itself as a feature or combined with solid colours for contrast.
Sowing Time
In Lahore, Faisalabad, Islamabad and Rawalpindi, sow Vinca seeds from February to April as the soil and daytime temperatures become warmer. Another sowing from late August through September can provide colour later in the season.
In Karachi and other mild coastal areas, January to March and August to October provide suitable sowing periods. The long warm season allows established plants to continue flowering for several months.
In southern Punjab and other very hot areas, February to March is a useful spring window. Late August and September provide another opportunity as the strongest summer heat begins easing.
In colder northern and hilly areas, sow from March to April when warm conditions have arrived and the risk of frost has passed.
Best Conditions
-
Sunlight: At least 6 hours of direct sunlight
-
Soil: Loose, fast-draining potting mix or garden soil
-
Sowing depth: Approximately ⅛ inch
-
Spacing: Around 10 to 12 inches between plants
-
Watering: Water when the upper 1 to 2 inches of soil begin to dry
-
Temperature: Warm conditions around 21°C to 24°C support germination
Cover the seeds lightly with seed-starting mix and keep the growing medium evenly moist. Place the tray in a warm, shaded position until the seedlings emerge, then move it into bright light.
A seedling tray makes it easier to manage warmth and moisture during the early stage. Transplant each seedling after it has developed several healthy leaves and a firm root system.
Pots and Beds
Most annual Vinca varieties develop into compact, branching plants approximately 8 to 18 inches tall. Their mature spread commonly reaches 12 to 18 inches, depending on the variety and growing conditions.
One established plant can fill a 10 to 12-inch pot. Wider containers and long planters can hold several plants spaced approximately 10 to 12 inches apart.
For a coordinated border, repeat one F1 colour along the planting area. A combination of solid and halo varieties creates a more varied display, while Vinca Mix provides several colours from a single sowing.
Choose containers with drainage holes and fill them with a light potting mixture. Vinca also grows well in grow bags, raised beds and open garden soil with good drainage.
Plant Care
Water around the base of each plant after the upper soil begins to dry. Established Vinca plants handle warm weather well when their roots receive moisture and excess water can drain freely.
A sunny position encourages compact growth and regular flowering. Plants growing on rooftops and balconies benefit from a location with bright morning sun and good airflow.
Feed lightly during active growth with a balanced flower fertilizer. Regular, moderate feeding supports new branches and a steady supply of flower buds.
Vinca naturally maintains a tidy appearance as older flowers fall away. Light trimming can shape spreading branches and encourage fresh growth during the middle of the season.

FAQs
How long do Vinca seeds take to germinate?
Vinca seeds commonly germinate within 7 to 14 days when the growing medium remains warm at around 21°C to 24°C. Cooler conditions can extend the germination period.
Will Sada Bahar return next year?
Sada Bahar can live as a short-lived perennial in warm, frost-free areas. In colder locations it is commonly grown as an annual and replanted from seed when warm weather returns.
Does Vinca require deadheading?
Annual Vinca usually continues flowering without regular deadheading because older flowers naturally fall away. Occasional tidying keeps pots and borders looking neat.
Can Vinca seeds be sown directly in a pot?
Seeds can be started directly in their final pot when the soil is consistently warm. Starting them in a covered seedling tray provides closer control over warmth and moisture during germination.
Are annual Vinca and Vinca vine the same plant?
Annual Vinca, or Catharanthus roseus, is the warm-season flowering plant commonly called Sada Bahar. Vinca vine refers to a different group of spreading groundcover plants.
