This tall flowering stalk is elkweed (Frasera speciosa), also called monument plant or green gentian and was once known as Swertia radiata. It's in the Gentian Family (Gentianaceae), and has a fascinating life story.The plants produce basal leaves, sometimes up to 80 years, before a flowering stalk emerges. Once the plant flowers, it dies, a trait that makes it a monocarpic plant. It appears that there are flowering outbreaks, when many plants in a close area flower in the same year.
From a distance, the flowers don't appear conspicuous among the horizontal cauline (along the stem) leaves.
A closer look shows the interesting flowers, with their lavender highlights on the green background. Flowers usually have four petals, but can have five.

Great to see these plants live through your camera lens! We have a relative of this Gentian family member, similar in looks and up to 8 foot tall- American Columbo.
