Common Name The Formosa Pleione - in China Tai Wan Du Suan Lan

Flower Size 3 to 4" [6 to 10 cm]

This is a small sized, cold growing terrestrial or lithophyte growing in moss on sunny rocks or on tree trunks in moist foggy areas found near the treeline in shaded locations in the mountains of Formosa at elevations of 1500 to 2500 meters with compressed, ovoid to ovoid-conical pseudobulbs carrying a single, apical, erect to arcuate, oblanceolate to elliptic, plicate, acuminate, deciduous leaf that is shortly petiolate and blooms in the late winter and early spring with one or two flowers per erect, 10" [to 22 cm] long, inflorescence which arises basally as a new growth appears. The growth of the psuedobulbs begins in the spring as it blooms and they will grow vigorously all summer until the onset of the fall which will cause the growth to stop and the leaves will drop, as this passes it is time to curtail watering and fertilizing until the process begins anew in the early spring.

This species is within the P bulbocodioides complex which includes P bulbocodioides, P limprichtii, P plenoides, P formosana, and P chunii .
