 B. telmatiaea is rarely cultivated . It grows fairly quickly , but tends to become untidy as it ages . The flower spikes , though attractive , occur within the bush where they are usually obscured by foliage . In its natural habitat it flowers prolifically over several months , but according to George it may be reluctant to flower in cultivation . It tolerates light pruning not below the green foliage . George recommends a sunny position in poorly drained soil , preferably with moisture in winter . Seeds do not require any treatment , and take around 14 days to germinate .
