The Compositae or aster family is vast, with over 20,000 species, and
is also one of the most developed families. It was named Compositae
because the flowers are actually a "composite" of many individual
flowers into one head. Hence, when children pull one "petal" off at a
time, saying "she/he loves me, loves me not", they are actually
removing a complete flower, not just a petal. Scent of foliage deters insects, roots exude chemical that repels soil nematodes. Marigolds often interplanted with crops or other ornamentals for pest control. The specific epithet name "erecta" means upright. Appropriately named Mary s Gold, these were the flowers of the Virgin Mary and were used to decorate church altars. Sometimes fed to chickens to improve yolk color. Suitable for drying. According to Creasy (1999), fresh petals are edible. Can be used in deviled eggs and butter and sprinkled over broccoli and other strong flavored vegetables. T. erecta are generally taller, have bigger flowers and their flowers often consist of one color whereas T. patula are shorter, smaller and have bicolored flowers. | |
