Alstroemeria is a genus of flower from South America that's a part of the larger Alstroemeriaceae family. These plants are related to lilies and bomareas, having the same unique leaves and vibrant flowers.
Definition
The Alstroemeria genus contains 50 species of plants and is also known as the Lily of the Incas. These flowers are commonly found in central Chile, where they are winter-growing, and in eastern Brazil, where they are summer-growing in cool mountain climates.
Shape
Alstroemeria flowers are slightly zygomorphic, meaning that they are bilaterally symmetrical, or distributed equally on each side. One half is a close but not exact mirror of the other. The flowers are typically arranged in a triangle shape, with two petals on either side of a single petal.
Petals and Sepals
Both the striped petals and the sepals, which are the leaves between the petals, come in an arrangement of three each. The petals and sepals have similar color and texture, so the sepals actually resemble the petals much more closely than they resemble most green leaves. The colors are varied and may come in pink, orange or red.
Reproductive Structures
Alstreomeria plants contain six undivided stamens, which are the male reproductive stalks extending from the center of the flower. The ovaries of the flower have three carpels and are known as inferior, because they are fused to the base floral structure.
Leaves
Alstroemeria plants are like grasses, irises and lilies in that veins go up to the leaves but do not branch across. These leaves are actually upside down because they twist as they extend from the stem. This feature is known as being resupinate.
