Leucaena leucocephala, the white leadtree jumbay or white popinac, a small tropical tree species
Based on the Masters research of Tyrone Kalpee, (now of BP), an innovative plan for the restoration of the bare-rock surface of the formerly quarried areas (which make up about 3/4 of the Hill) was developed based on Leucaena leucocephala, a fast-growing leguminous tree species.
Some allelochemicals even have selective effects on surrounding organisms; for example, the tree species Leucaena leucocephala exudes a chemical that inhibits the growth of other plants but not those of its own species, and thus can affect the distribution of specific rival species.

Adults feed on the nectar of various flowers, including Leucaena leucocephala, Melilotus alba, Cynoglossum amabile, Bidens alba, Turnera ulmifolia, Mimosa pudica and Acacia species.
Its hot, dry climate is suitable for Plumeria and Bougainvillea cultivars in the outer crater, kiawe (Prosopis pallida) and koa haole (Leucaena leucocephala) trees, and four major collections organized by region (Africa, the Americas, Hawaii, Madagascar).
