Brighamia insignis

A Hawaiian cliff plant, now extinct in the wild, with a swollen succulent stem topped by a rosette of fleshy leaves and fragrant white tubular flowers. In cultivation it wants warmth, bright light, a sharply drained mix and careful watering. Cold and soggy soil kill it quickly.

Where it grows wild

Formerly grew on steep sea cliffs and rocky ledges with thin soil, in mesic shrubland and dry forest on Kaua'i and Ni'ihau. Hurricanes and landslides wiped out the last wild plants.

Sea level to about 480 m. The 3,212 m measured site is a cultivated or misplaced record on Hawai'i Island.
