Hapuu

Hāpuʻu tree ferns (Cibotium glaucum and related species) are iconic understory plants in Hawaiʻi’s native rainforests. Although not a traditional timber species, they are found widely in volcanic, humid regions of the island.

Hāpuʻu ferns are typically harvested for their fibrous trunk material used in horticulture (as a growing medium) and landscaping. The pith is sometimes utilized for planting orchids or other epiphytic species. However, they are not processed into wood products in the conventional sense, so they don’t form a direct part of the lumber market. Conservation guidelines restrict wild harvesting in many locations, emphasizing sustainable harvest or farm cultivation to maintain ecological balance.
