Each year, the National Garden Bureau highlights standout crops, and for 2025, Calendula, also known as pot marigold, takes the spotlight as an Annual of the Year. Loved for its vibrant blooms and versatility, this resilient flower is perfect for seasoned and new gardeners alike.

A bloom with history

Calendula’s story is as colorful as its petals. Native to the Mediterranean, this cheerful flower has been celebrated for centuries. Ancient Egyptians admired its healing properties, while Romans introduced it across Europe, where it became a staple in gardens and kitchens. Dubbed “poor man’s saffron,” calendula petals can be used as a natural yellow dye or to flavor and color recipes.

How to grow calendula

Calendula thrives in cool weather, making it ideal for early spring and fall planting. Follow these tips for success:

Planting basics

• Direct sow seeds in early spring, even when light frosts are possible. Continue sowing every two to three weeks until early summer for a staggered fall bloom.
• Starting indoors? Sow seeds in late winter. 
• Sow seeds 1/4 inch deep and cover completely; they require darkness to germinate.
• After germination, place them under bright lights.
• Space plants 6–18 inches apart for healthy growth. Pinch back young plants to encourage branching.

Care and maintenance

• Provide full sun and well-drained soil, with a pH between 5.5 and 7.
• Water regularly but avoid wetting leaves to prevent mildew.
• Deadhead faded blooms to promote continuous flowering.

Why gardeners love calendula

Calendula’s beauty comes with added benefits, making it a garden favorite:

• Natural pest control: Planted near vegetables like tomatoes and beans, calendula attracts beneficial insects while keeping pests at bay.
• Edible and delicious: Its petals add a peppery flavor and vibrant color to salads and soups.
• Medicinal properties: Harvest flowers to dry for teas, soothing salves, or fragrant potpourri.

A bloom for cool seasons

Calendula thrives in cool weather but may pause blooming during hot summers. Don’t worry—it bounces back with vivid blooms as temperatures drop, bringing a burst of fall color.

Whether you’re brightening your garden, attracting pollinators, or exploring its edible and medicinal uses, calendula is a plant that truly gives back. Its rich history, ease of care, and versatility make it a must-have for any garden.
