Calendula (pot marigold) is a cheerful and versatile annual that brings both beauty and utility to the garden. Its vibrant flowers, ranging from yellow to bright orange, are not only decorative but also edible, adding a pop of color and a mild flavor to salads, teas, quiches, or baked goods.

Calendula's medicinal properties make it a must-have in herbal medicine, especially for soothing skin irritations or for making infused oils and balms. It is highly attractive to pollinators, easy to grow, self-seeds readily, and offers continuous blooms throughout the season.

Calendula thrives in zones 3 to 9. It prefers full sun to partial shade and well-drained soil. It is perfect for flowerbeds, borders, and containers, and fits beautifully into pollinator or cottage-style gardens.
