Calendula ‘Greenheart Orange’
Calendula officinalis
Description
This double-flowered beauty is the tallest calendula we’ve ever grown. Eye-catching blooms are a glowing pumpkin-orange color, and long, strong stems make them a must-grow variety for flower arranging. Calendulas are easy to grow and the fastest flowers to bloom from seed—in just 2 months. Often called English marigolds, the plants are loved by beneficial insects. Petals can be used as fabric dye, are edible, and can be used medicinally in salves.
