Puya alpestris is a succulent whose blossoms are a surprising shade of turquoise. I have never seen any plant with flowers anything like this color. If I didn’t see it with my own eyes, I would have assumed these photos were altered. What luck to get to see this plant in bloom on my recent visit to the San Francisco Botanical Garden. It seems so alien, or perhaps like something that belongs under the sea.
The plant produces a tall spike that blooms with hundreds of teal flowers. It was quite a bit taller than me.
“Puya alpestris from Chile is in the bromeliad family, which includes many plants with fibrous, spiky edged leaves. It is one of the most dramatic and beautiful plants when in bloom, as it sends up a flower stalk to 6′ with bright turquoise flowers.” Source
