Alstroemeria, commonly called the Peruvian Lily or Lily of the Incas or Parrot Lily. Alstroemeria is a slightly zygomorphic (bilaterally symmetrical) flower with 3 sepals and 3, generally, striped petals. The sepals and petals on the Alstroemeria are similar in color and texture – i.e., there are no solid green sepals. Alstroemeria has six stamens and an undivided style. The ovary on the Alstroemeria is inferior, with 3 carpels. Alstroemeria features a monocot plan of having floral parts in 3s.
Alstroemeria is more like grass where the veins go up the leaves but none branching across. This can also be seen in grasses, Irises and Lilies. Alstroemeria leaves are upside down. The leaf twists as it leaves the stem, so that the bottom is facing upwards.
