Eurybia kingii
King's serpentweed (Eurybia kingii) is a small, rare perennial daisy from Utah, rarely over 12 cm tall, growing from a woody underground base. It is a wild species of conservation concern, so it is not commonly grown in gardens.
Eurybia kingii is a North American species of flowering plants in the family Asteraceae, called the King's serpentweed or King's aster. It has been found only in the State of Utah in the western United States.
Eurybia kingii is a small perennial herb rarely more than 12 centimeters (2.8 inches) tall from a woody underground caudex. The plant produces flower heads in groups of 1-5 heads. Each head contains 13-27 white or lavender ray florets surrounding 29–47 yellow disc florets.
Eurybia kingii is limited to just seven counties in Utah in the western half of the state, Box Elder, Cache, Webber, Salt Lake, Utah, Juab, and Millard. Eurybia kingii was evaluated by NatureServe as "Vulnerable" (G3) in 1999, with the same rank at the state level because it endemic to Utah.
