Hutchinson had been established 65 miles(105 km) southwest of Hilo on the Big Island of Hawai'i in 1868, making it one of the oldest sugar plantations in the islands as well as the one that lay farthest south. Renamed Naalehu Sugar Plantation for the mill's town soon afterward, it reverted to HSP in 1879 when Hutchinson died and William G Irwin and Claud Spreckels bought the assets.
The Plantation Archives entry notes that this was a small plantation that nonetheless grew cane on 7 1/2 sq miles (1,943 hectares) from sea level to 2,000 feet (610 metres). The altitude and variable rainfall affected growing times, say the authors: "The bulk of the cane lands were above the 1,600-ft.[488 metre] level. The cane at the lower levels of the plantation matured in 18 months, whereas, the cane at higher elevations required from 24 to 30 months to mature."
In addition to the eight miles (13 km) of railway, the plantation used 70 miles (113 km) of flumes to transport the cane to the mill.
C Brewer & Company bought the company in 1910, but retained the name.
