Dracaena fernaldii

Lanai hala pepe

Lanai hala pepe is a small branching tree, 3-10 m tall, found only in the dry forests of Lānaʻi in Hawaiʻi at 490-670 m. It is federally listed as endangered, with roughly 400-1,000 plants left and very little young growth in the wild. In cultivation it needs strong light, warmth and a free-draining soil, and becomes quite drought-tolerant once established.

Where it grows wild

It grows in dry to mesic lowland forest on the slopes of Lānaʻi, among other native dry-forest trees. Much of that forest has been degraded by grazing and invasive plants, and the cause of the poor seedling recruitment is unclear.
