Family Name: Amaryllidaceae
Native to: Ecuador and Peru
The Eucrosia bicolor is related to the amaryllis and daffodil. It grows from a bulb and produces multiple red and yellow flowers on each stem. Most notable are the yellow stamens with long prominent filaments. Stamen are the reproductive pollen-producing organs of a flower, that consists of a filament (stalk) and an anther (contains the pollen grains). Eucrosia flowers are thought to be adapted for butterfly pollination. The red flowers attract the insects and the long filament ensures the pollen is deposited on the butterfly as it collects nectar.
This Peruvian lily is in an entirely different family than the Peruvian lily commonly used in flower arranging and Bay Area gardens, the Alstroemeria. This is a great example of why botanical names are used whenever possible.
