The Pot Marigold is a favorite of children gardening: its seeds are big, germinate readily and produces showy flowers. It also provides good cut flowers.
The pot marigold flowers were made into an ointment to releave minor burns. Its petals can be used fresh in salad, or dried to flavor rice.
Check for slugs, aphids and powdery mildew.
Self seed readily. In Phoenix, seed in place in the fall. In colder areas, seed inside at 65°F (18°F) 8 weeks before the last frost. The seeds should be covered with some soil since light tends to inhibit germination. They germinate in 1 to 2 weeks. Plant 6 week-old plant outside, 12 inches apart (30 cm), even if you expect some frost. Watch for aphids and powdery mildew.
