Mr. Edward Henry Harriman organized and led the Harriman Alaska Expedition in 1899 taking his whole family along. This plant was named for Mrs. Harriman.
This plant has a deep taproot (at least 30' long).
Yucca used to be in the Liliaceae (Lily) family.
Did You Know?
Lizards, including the colorful collared lizard, are one of the most frequently seen animals at Arches. When not chasing flies or basking in the sun, they are often seen doing what appears to be push-ups. This odd dance might enhance their stereoscopic vision, helping them see what's looking back at them.
