Alstroemeria, commonly called the Peruvian Lily or Lily of the Incas, is a South American genus of about 50 flower, mainly from cool, mountainous regions in the Andes. It is sometimes called 'Ulster Mary' (as a word corruption).
The plants are tuberous or rhizomatous perennials. The young plant starts growing from the main rhizome. Another 5 to 7 rhizomes start growing from the main rhizome, sending up, per year, between 60 to 80 flowershoots. They grow to a height of 50-130 cm.
Each erect stem grows a handsome foliage of a few lanceolate leaves, and ends in an umbel of colorful flowers. These have 6 petals with spots, striped markings and contrasting patches.
This gorgeous flower, which resembles a miniature lily, is very popular for bouquets and flowers arrangements in the commercial cut flower trade. They are considered by some to be among the most beautiful cut flowers on earth, even if the vase life doesn't last any longer than two weeks. Many hybrids and about 190 cultivars have been developed, with different markings and colors, ranging from white, golden yellow, orange, to apricot, pink, red, purple and lavender.
