The Aztec plant (Sprekelia formosissima), or Aztec lily, as it is more commonly known, is a perennial flowering plant in the amaryllis family. Native to Mexico and Guatemala, the Aztec plant blooms in bright scarlet to deep red flowers in late spring or early summer. Aztec plants are frost-intolerant but do well grown in pots in cooler regions of the country.The Aztec plant is hardy in USDA zones 8 through 11.
Place the Aztec plant where it receives full sun all day. In hotter areas of the country, provide afternoon shade.
Water the Aztec plant to keep the soil consistently moist. Reduce watering to half the amount when the foliage begins to fade and dry. Discontinue watering while the Aztec plant is dormant.
Fertilize the Aztec plant every two weeks during the growing season with a liquid 20-20-20 fertilizer at the rate specified on the label.
Cut the old flowers from the stem when the stem begins to bend. Cut it back to within 2 inches of the surface of the soil.
Protect the outdoor Aztec plant by covering it with mulch before the first frost.
