Summary

An Hawaii-endemic lobeliad in Campanulaceae with a candelabra-like, woody shrub or small tree growth form reaching 1–6 m, and large leaves 12–26 cm long adapted to semi-shaded habitats; it occurs in mesic forests and forest margins on Maui, Molokaʻi, and Oʻahu, at elevations roughly 120–1,270 m; showy flowers are greenish-white to white externally with dark purple interiors, and berries ripen as large orange fruits; the species may be terrestrial or epiphytic.

Cultivation and uses: growth is difficult and highly pest-sensitive, with slugs, snails, and red spider mites; protection from strong afternoon sun, consistent moisture, and vigilant pest control are essential; moist, well-drained soils with partial sun are preferred; container culture can use a mix of equal parts peat, perlite, and black cinder plus native compost with mycorrhizal fungi, with regular fertilization; in-ground plantings require shade, moisture, slug/snail control, and frequent watering; historically, leaves were boiled and berries eaten fresh by ancient Hawaiians.
