This member of the Campanulaceae family was described by Harold St. John in 1969. It is only found on the Hawaiian island Molokai. It grows on the hill-sides in well-drained soil with some water and lots of sun. It can grow to 5 meters with a stem 25 centimetres in diameter, and the flowers are white. Forrest Anderson send me some seeds from CSSA seed depot.

Prefer temperatures around 20-25 C.

The genus name: Brighamia, is named after William Tufts Brigham, 1841-1926, geologist, botanist and the first direction of the Bernice P. Bishop Museum, Honolulu, Hawaiʻi. The specific name rockii is named for Joseph Frances Charles Rock,1884-1962, an Austrian-American botanist who did much to help our current understanding of native Hawaiian plants.

Sadly, there are now fewer than 200 Brighamia rockii, plants growing on Moloka’i, I'm told.
