Manning and Goldblatt's Cape Plants describe it as a twining tuberous perennial. This books says it has a wide distribution from Namaqualand and the Western Karoo to Port Elizabeth where is grows on sandstone and clay slopes (habitats I'd expect more likely than grassland for some of those areas) so must grow in some areas where there is very little rainfall and that mostly coming in the winter months although those growing in Port Elizabeth would have different conditions. I looked up some other species in my Namaqualand field guide and they were described as deciduous perennials growing from a tuber. Our group never will reach consensus about what is appropriate for discussion or probably even what is a geophyte and the leadership has erred on the side of being inclusive and has allowed pictures of plants with tubers, corms, bulbs, rhizomes, even tuberous roots to be added to the wiki. Certainly other plants that have a dormancy period and grow from a tuber are considered geophytes. In nature given where it grows there would be little to no moisture. Does anyone else grow it who could offer an opinion about the care it needs in summer to thrive? Mary Sue >Is this species considered a geophyte (how not, I suppose)? How complete >a summer rest does it need?
