Frasera Speciosa
''Frasera speciosa'' is a species of flowering plant in the gentian family (Gentianaceae) known by the common names elkweed, monument plant, and green gentian. When blooming it grows a tall stalk with numerous flowers that have purple dotted green petals. Each plant can flower just once before it dies. Description ''Frasera speciosa'' is a very large plant that flowers once before it dies (monocarpic), but may live for many years before flowering. Plants that are not yet ready to flower are made up of strap like leaves with short stalks in a low cluster (basal leaves). Though not as striking as the very tall flowering stalk, this stage of growth is quite unique in appearance and size in their range. The basal leaves are green with a waxy coating (glaucous) and 7–50 centimeters long and 1–15 centimeters wide. Their shape is like a spoon with a narrower base (spatulate) to being much longer than wide and with the widest portion near the tip (oblanceolate) with either a ...
