Though they will grow outside in Britain this Beesia calthifolia was in the shelter of the Cambridge Botanic Garden alpine glasshouse. It comes from mountainous forests in China, having glossy green leaves and upright spikes of starry white flowers followed by these sculptural seed pods. This plant thrives in semi-shaded moist, well drained soil.
