Harvest Tips

Fun Facts
- 🌱 Marigolds are sometimes called 'calendula' in culinary contexts, though true culinary calendula is Calendula officinalis—a different plant entirely.
- 🌱 The term 'double' refers to the extra petals created through selective breeding; these flowers have many more petals than the typical single marigold form.
- 🌱 Marigolds naturally repel certain garden pests and are a traditional companion plant in vegetable gardens, earning them the nickname 'poor man's saffron' in some cultures due to their golden color.
