Pot marigold - Calendula officinalis

Cool-hardy, fast-establishing perennial prized for bridging seasonal nectar and pollen gaps in functional farm systems. Flowering early in spring and well into autumn, its open composite blooms sustain vital predatory insects—especially hoverflies, minute pirate bugs, and parasitoid wasps—supporting early-season biological pest suppression before warm-season annuals take off. Resilient across a range of soil types, Calendula is a dependable addition to insectary blends, under-vine swards, and market garden borders.
