Calendula Sunset Buff produces soft apricot-buff flowers with warm peach and cream tones. The petals have contrasting crimson-red backs, which become more visible when the flowers close or move in the breeze. Its unusual colouring gives pots, borders and flower arrangements a softer appearance than standard orange Calendula.

Native to southern Europe and the Mediterranean region, Calendula grows best during cool, mild weather. Sunset Buff is an open-pollinated variety with upright, branching stems that flower through Pakistan’s winter and early spring.

Why Grow It

• Sunset Colours: Flowers combine soft apricot, buff, peach and cream shades.
• Dark Petal Backs: Crimson-red undersides create an attractive colour contrast.
• Cut Flowers: Upright stems are suitable for vases and arrangements.
• Pollinator Friendly: Open flowers attract bees and other visiting insects.

Best Conditions

• Germination: Usually 7–14 days
• Temperature: Around 15–22°C
• Sunlight: At least 6 hours
• Pot size: 8–12-inch-wide pot or larger
• Spacing: About 8–12 inches between plants
• Plant height: Usually around 18–24 inches
• Soil: Light, moderately fertile and well-draining mix

In Lahore, Faisalabad, Islamabad and Rawalpindi, sow from September to November, or again from late January to February. In hotter areas such as Karachi and southern Punjab, sow from October to December after the strongest summer heat has eased. In colder northern and hilly areas, sow from March to April after the risk of hard frost has passed.

How to Sow

Calendula Sunset Buff is easy to sow directly in its final pot or flower bed, although it can also be started in small pots.

1. Fill the container with fine, moist and well-draining potting mix.
2. Make shallow holes or rows around ¼ inch deep.
3. Sow the seeds thinly and cover them lightly with the mix.
4. Water gently and keep the soil lightly moist until seedlings appear.
5. Thin young plants after 2–3 true leaves develop, leaving 8–12 inches between them.

Plant Care

Water when the upper layer of soil begins to dry. Keep young plants evenly moist while they establish, but avoid leaving the roots waterlogged. Water near the base early in the day so the leaves remain dry overnight.

Mix a small amount of Vermicompost into the soil before sowing. Calendula needs only light feeding. Excess fertilizer can produce abundant leaves with fewer flowers.

If aphids gather around the tender shoots and buds, spray Neem Oil on the affected growth during the evening. Avoid spraying open flowers.

Local Gardener Tips

• Protect newly sown pots from forceful watering and heavy rain.
• Give plants full winter sun for stronger stems and better flowering.
• Pinch young plants once for more flowering branches.
• Leave space for airflow during foggy and humid weather.

Flowering

Plants usually begin flowering around 8–10 weeks after sowing. The apricot-buff petals may become slightly lighter as each flower matures, while their crimson-red backs remain visible around the edges and when the blooms begin closing.

Remove faded flowers regularly to encourage further buds. For vases, cut the stems when the flowers are about halfway open and place them in clean water promptly.

FAQs

Why do Calendula flowers close in the evening?

Calendula flowers naturally respond to lower light and may close during evenings, cloudy weather or rain. They usually reopen when brighter sunlight returns.
