Monument Plant
Frasera speciosa
Gentian family (Gentianaceae)

Green Gentian grows for 20-60 years. The plant then develops a 4-7 foot bearing 600 flowers that produce 60 seeds each to give rise to the next generation. The dried persists through winter. Plants with life cycles such as this are called "," i.e., growing for many years without flowering and then flowering and immediately dying after the seeds develop. Green Gentian was first collected for science by David Douglas (of Douglas Fir fame) in the present-day Spokane area in the early 1830s. The name, "Frasera," is for John Fraser, 18th century nurseryman and botanist. "Speciosa" ("showy") is for the leaves and massive display of flowers.
