Showy green gentian, Frasera speicosa, is a very interesting plant with beautifully ornate blossoms on long green stalks. This monument plant, like the agave century plant of the southwest, can live for decades before sending up a tall spike of flowers and dying from the effort. Sometimes all the plants in an area bloom at once, creating quite a worthwhile scene.
The full, basal leaves are also attractive, forming pretty bushes in open meadows. This species can also go by the names elkweed or deer’s ears and can be found throughout the west.

The flowers are often greenish white, but sometimes they have purple accents that make them even more spectacular. And the caterpillars think so, too.
