About Calendula

Calendula (Calendula officinalis), also known as pot marigold, is a cheerful and versatile annual that brings beauty and practicality to your garden. Its vibrant orange and yellow blooms are not only stunning but also edible, adding a pop of colour and mild flavour to salads, teas, quiches, or baked goods.

Calendula’s medicinal properties make it a staple in herbal remedies, often used for soothing skin irritations or crafting infused oils and salves. A favourite of pollinators, it is easy to grow, self-seeds readily, and provides an ongoing display of blooms throughout the season.
