Growing Calendula in Zone 2A

Calendula (pot marigold) is a cool-season flower with medicinal properties and cheerful blooms.

Zone 2A has a short growing season — start seeds indoors when possible and use season-extending techniques like cold frames and row covers.

Top Growing Tips

• Prefers cool weather — blooms best in spring and fall
• Self-seeds prolifically — you’ll have it forever after one planting
• Petals are edible — use as ‘poor man’s saffron’ in cooking
• Attracts beneficial insects including hoverflies and lacewings
• Used in herbal salves and skin care for centuries

Companion Planting

Good companions: tomatoes, asparagus, virtually everything

Avoid planting near: none — calendula is a universal garden friend

Harvest Timeline
