Calendula 'Greenheart Orange'

Greenheart Orange Calendula (Calendula officinalis)

Radiant and bold, Greenheart Orange Calendula blooms in glowing shades of pumpkin orange—each double flower luminous against its dark green foliage. The petals fold in layered spirals, their golden glow softened by a subtle green tint at the heart. Tall and graceful, the stems rise with poise, carrying blossoms that feel both rustic and regal, like a harvest sun suspended in bloom.

A favourite among pollinators and designers alike, Greenheart brings warmth and texture to every arrangement. Pair with Kees’ Orange Marigold for a glowing, sun-drenched palette, or with Linen Zinnia for an earthy, neutral contrast. A flower that embodies abundance, joy, and the quiet fire of late-summer light. Also known as English Marigold or Pot Marigold.

HOW TO GROW:
Direct Seed (recommended): Sow seeds directly outdoors after the last frost. For continuous blooms, make 2–3 successive sowings 2–3 weeks apart, from summer through to heavy frost.

Transplant (alternative): Start seeds indoors 4–5 weeks before the last frost. Harden off seedlings by gradually exposing them to outdoor conditions before transplanting outdoors after the last frost.

Pinching: Pinching the tops of young plants can encourage a bushier habit and more blooms.

Soil Preference and Watering: Calendula prefers full sun and well-drained soil. It is very adaptable to a wide range of soil conditions. Water consistently, but avoid overwatering.

Fertilizing: Fertilizing is not required for Calendula. It performs best in average to lean soil.

Harvesting: Harvest calendula flowers when they are fully open. The petals are edible and can be used to garnish salads or other dishes.

Other Tips: Calendula may self-seed if allowed to mature at season’s end.
