ALSTROEMERIA (Peruvian Lily, Lily of the Incas) A. species Amaryllidaceae
HABITAT: Native to Chile, Brazil. Zone 6-10 dependent upon species.
USES: Borders, cut flowers.
HABIT: Tender, fibrous rooted (white, brittle, rhizome-like roots) plants bearing massive clusters of 1 1/2-2" lily-like orange, yellow, lilac, pink, or red flowers atop 1-4' stems. The fragrant flowers, many of which are streaked with brown or green, flower from early summer to mid summer.
SEED GERMINATION AND CULTURE: Sow in winter, 8-10 weeks before setting out in spring. Spread moist Grow Mix in a shallow tray. Sow seeds in rows 1/4" deep and cover. Put tray in a warm place 68° F for 30 days. Then put tray in a cool place, 40-50°F until germinated. Set young plants or the roots in full sun in well-drained soil, 5-8" deep and 12" apart. Set roots horizontally. Stakes may be needed to support plants in windy locations. Incorporate humus and 2 oz. of super-phosphate per square yard into the soil mix prior to planting. Spade the soil deeply to 15-18". Keep well watered and in the zones where plants are left in the ground over winter apply a mulch of hay, straw, etc. for winter protection. Plants may be grown in 8-12" pots using a commercially prepared potting soil or 1 part soil, 1 part sand, 1 part peat moss, and 3-5 oz. of limestone per bushel of soil mix. In cold climate, place the containers in a cool (above freezing) location over winter.
