Calendula officinalis A juicy blend of sunny colors from creamy ivory to lemon and through shades of apricot and orange. As easy and simple to grow as any calendula, Cantaloupe produces big, double blooms throughout the summer, but keep in mind that deadheading encourages the production of flowers. An exceptional pollinator attraction as well as cutting flower. A wonderful naturalizer, Cantaloupe will readily re-seed. Here in our zone 8 gardens, it’s not unusual to find sporadic flowers throughout the winter. Approximately 100 seeds per gram.
