Isodendrion hosakae
Also called Aupaka
Cindercone isodendrion (Isodendrion hosakae) is a rare, federally endangered shrub from Hawaii, growing only on cinder cones on the island of Hawaii. It is not a common garden plant, so care is best guided by its wild conditions: exposed, windy, foggy sites with good drainage.
Isodendrion hosakae is a rare species of flowering plant in the violet family known by the common names cindercone isodendrion and aupaka. It is endemic to Hawaii, where it is known from fewer than 1000 individuals on the island of Hawaii. It is a federally listed endangered species of the United States.
This is a shrub growing up to about 80 centimeters in maximum height. The lance-shaped leaves are about 2.5 centimeters long. It produces fragrant greenish yellow flowers each about 1.3 centimeters long.
