1019 Sprekelia formosissimaCommon Names: Aztec lily, Jacobean lily, St. Jame's lily, orchid lily Family: Amaryllidaceae (amaryllis Family)
Aztec lily is like other members of the amaryllis family: It is a bulb that produces a rosette of strap shaped leaves and a single, showy flower with six tepals. The leaves grow to about 20 in (50 cm) long and come out in spring about the same time as the flower. The flower is about 5 in (13 cm) across and brilliant scarlet or crimson. The flowers are bilaterally symmetrical, like an orchid: they have a broad, erect upper tepal, 2 narrow lateral tepals, and three narrow partly fused hanging tepals. The flower stands on its scape about 12 in (30 cm) above ground, and the bulb itself is about 2 in (5 cm) in diameter. Named cultivars include a white flowered lily, one whose red tepals are edged in white and one that has a golden strip down the center of the upper tepal.
Sprekelia formosissima is the only species in the genus. It occurs naturally in Mexico and Guatemala, characteristically on rocky hillsides.
CultureLight: Grow Aztec lilies in full sun. Moisture: Treat Aztec lilies like any other bulb; they like plenty of water when putting out new leaves and when blooming, but they like it dry when dormant. Hardiness: USDA Zones 8 - 11. Aztec lily is nearly frost-tender, but it can be grown in climates that receive only light frosts, as long as the bulb is protected in winter with some mulch. Propagation: Little offset bulblets can be separated and replanted in autumn. Plant the bulbs so that the top (neck and shoulders) are just above ground level.
Some people grow Aztec lilies in a pot. Potted lilies should be kept in full light when growing. As the leaves fade, reduce watering and then keep dry while dormant. Aztec lilies can be grown outdoors in areas that get frost, but they must be lifted in late autumn and stored dry in a frostfree location.
Aztec lily is sometimes sold under the name Amaryllis formosissima. The amaryllis family gives us many popular garden bulbs including magic lily (Amaryllis belladonna), crinum lily (Crinum asiatica), hurricane lily (Lycoris radiata), the daffodils (Narcissus spp.), and atamasco lily (Zephyranthes atamasca).
