Discussion | Cultivars of Tagetes erecta are widely grown in gardens and, commercially, for cut flowers. They often persist after abandoned plantings. Tetraploid plants (2n = 48) with smaller involucres and wholly or partially red-brown corollas included here in T. erecta have been called T. patula by some botanists.
