A Marigold
TAGETES
French marigold (T. patula) is the low-growing, familiar type. Their colors reside on the yellow, orange and red side of the color wheel, which makes them great foils for plants with purple flowers. Tagetes erecta is the African marigold, which not only grows much taller than its cousin — up to 48 inches — but also offers cultivars with large white blooms. Both types want lots of sun, fertile soil and regular watering.
