If you’re curious about the difference between marigolds and calendulas, this listicle is for you. Whether you’re a gardener, herbalist, or simply a flower enthusiast, understanding how these two popular plants differ can help you make better choices for your garden, skincare, or culinary uses. Here, we break down the key distinctions between marigolds and calendulas across ten important points.
1. Botanical Classification
Marigolds belong primarily to the genus Tagetes, with species like Tagetes erecta and Tagetes patula being widely cultivated. Calendulas, on the other hand, belong to the genus Calendula, with Calendula officinalis being the most common species. This difference in genus means they are related but distinct plants within the Asteraceae family.
2. Flower Appearance and Color
Marigold flowers tend to be fuller and more ruffled, often featuring vibrant shades of orange, yellow, and red. They typically have a more pom-pom or daisy-like structure. Calendula flowers are generally simpler, with a flat daisy-like shape and petals that range from bright yellow to deep orange, sometimes with a slightly paler center.
3. Growth Habit and Size
Marigolds can grow quite tall, especially Tagetes erecta, which can reach heights of up to 3 feet or more. They often form bushy clumps. Calendulas are usually smaller and more compact, typically growing 1 to 2 feet tall, with a bushy, spreading habit that makes them excellent for borders and containers.
4. Fragrance and Scent
Marigolds are known for their strong, pungent aroma, which some find unpleasant but is effective at repelling certain insects. Calendulas have a much milder, sweeter scent that is often described as slightly herbal or citrusy, making them more appealing for use in skincare and teas.
5. Edibility and Culinary Uses
Calendula petals are edible and commonly used as a colorful garnish or in salads, soups, and herbal teas. They have a slightly peppery, tangy flavor. Marigold petals from Tagetes species are edible too but tend to have a bitter taste and are less commonly used in cooking, though some cultures use them as a saffron substitute.
6. Medicinal and Skincare Applications
Calendula officinalis is widely recognized for its anti-inflammatory, antimicrobial, and wound-healing properties, making it a staple ingredient in creams, ointments, and herbal remedies. Marigolds have some insect-repellent and traditional medicinal uses, but they are less commonly used in skincare compared to calendulas.
7. Pest Control and Companion Planting
Marigolds are famous for their ability to deter pests like nematodes, aphids, and whiteflies, making them popular companion plants in vegetable gardens. Calendulas also attract beneficial insects such as pollinators and predatory wasps but are less effective as pest repellents compared to marigolds.
8. Hardiness and Growing Conditions
Both plants prefer full sun and well-drained soil, but marigolds are generally more heat-tolerant and drought-resistant. Calendulas can tolerate cooler temperatures and sometimes behave as short-lived perennials in mild climates, while marigolds are typically grown as annuals.
9. Seed Appearance and Germination
Marigold seeds are slender, dark brown or black, often with a slight curve, and germinate quickly within 5–7 days. Calendula seeds are lighter brown, thicker, and more oval-shaped, with a germination period of about 7–14 days. This difference can help gardeners distinguish seeds before planting.
10. Cultural and Historical Significance
Marigolds have a rich cultural history, especially in Mexico and India, where they are used in religious ceremonies and festivals like Dia de los Muertos and Diwali. Calendulas have a long history in European folk medicine and were once called “pot marigold” due to their culinary and medicinal uses dating back to medieval times.
How to Choose
When deciding between marigold and calendula, consider your primary purpose. For pest control and vibrant, heat-tolerant garden color, marigolds are your best bet. If you want edible flowers, skincare benefits, or a milder scent, calendulas are preferable. Also, think about climate: calendulas tolerate cooler weather better, while marigolds thrive in hot, sunny gardens. Finally, look at flower form and color preference—marigolds provide rich, dense blooms, while calendulas offer simpler, classic daisy-like flowers.
