The calendula, an old, English-cottage-garden flower is a long-blooming addition to any modern garden. Its gold and orange flowers bloom from spring to fall on fairly drought- and heat-tolerant plants. Grow it for attracting pollinators and its sunny beauty in the garden, then save some blooms for fresh or dried floral arrangements; dried petals can be used in baking or teas. Calendula gets its common name, pot marigold, because the flower resembles a marigold, and has often been used in pots of soup or stew for both color and flavor.
