From seed to bloom, we're here to help you grow.
Calendula (Calendula officinalis), sometimes called pot marigold, is a cool-season flowering plant known for its cheerful yellow and orange blooms. It can be grown in garden beds, containers, pollinator gardens, and alongside vegetables and herbs.
Calendula generally prefers the cooler temperatures of spring and fall and may slow down or stop flowering during the hottest part of summer.
Starting Your Seeds
Calendula can be started indoors or sown directly into the garden.
For an indoor start, sow seeds approximately ¼–½ inch deep several weeks before your expected last frost. Keep the growing medium evenly moist while the seeds germinate.
Calendula can also be direct-sown outdoors in early spring when the soil can be worked. In climates with suitable fall conditions, another sowing can provide a second season of flowers.
Once seedlings emerge, provide plenty of light and good airflow.
Planting Outdoors
Choose a location with full sun to partial shade and well-draining soil. In warmer conditions, some afternoon shade can help plants cope with heat.
If seedlings were started indoors, gradually harden them off before transplanting them permanently outside.
Space plants approximately 8–12 inches apart, adjusting as necessary for your growing conditions and the size of your plants.
Calendula also grows well in containers as long as the container has adequate drainage.
Growing & Flowering
Water regularly while plants become established. Once growing well, aim for consistent moisture without keeping the roots waterlogged.
Calendula doesn't generally require heavy feeding. Excess fertilizer can encourage leafy growth rather than abundant flowering.
Removing spent flowers—or deadheading—encourages the plant to continue producing blooms.
And if the weather gets hot and your calendula seems to slow down, don't immediately assume you've done something wrong. Calendula prefers cooler conditions and may perform better again as temperatures moderate.
Harvesting Flowers
Harvest flower heads when they're fully open and healthy.
If you're harvesting flowers for a particular culinary, cosmetic, or herbal purpose, make sure the plants have been grown and handled appropriately for that intended use. Never assume a flower is safe to consume or use medicinally simply because the plant is commonly described that way.
For Melanated Eden's Scan to Grow guide, I like keeping the emphasis on successfully growing the plant rather than making medicinal claims.
Saving Your Calendula Seeds
If you'd like to save seeds, stop deadheading some of your flowers and allow the spent blooms to remain on the plant.
Calendula develops distinctive curved seeds as the flower head matures. Allow the seed head to become dry before collecting it.
After harvesting, let the seeds finish drying thoroughly before storing them in a labeled container somewhere cool, dark, and dry.
If multiple calendula varieties are growing near one another, naturally occurring cross-pollination may mean saved seeds don't produce flowers identical to the parent plant.
Cool-Season Garden Note
Calendula gives you an opportunity to think beyond a single spring planting.
Try observing how it performs during different parts of your growing season. Record when it germinates, when flowering begins, how it responds to summer heat, and whether a later sowing performs differently.
That's part of learning your own garden rather than relying entirely on a calendar.
Keep Growing
Gardening is observation, patience, and learning season after season. Every planting gives you another opportunity to understand your soil, weather, plants, and growing space.
Take notes, experiment, save seeds when appropriate, and carry what you learn into your next season.
