I’ve been happily growing both Gem marigolds (tagetes tenuifolia), French marigolds (tagetes patula) and Giant/ African marigolds( tagetes erecta), and was wondering if someone can explain to me why the color variations within the shorter gem varieties of marigolds are so much greater than the giants? I can only find seed for white and orange Giant/African Marigold, and would love to find a giant marigold that had more interest beyond just a solid color. Thanks in advance!
