I purchased seeds of four different Chamaedorea species in June 2006. I received 12 radicalis (standard form) seeds and potted them all together in a 150mm (6") pot using a mixture of coir, sand and potting compost. The pot was watered then wrapped with cling film and left in my polytunnel with ambient temperatures of 22-32°C (72-90°F). By September nine had sprouted. The germination rate on both radicalis forms was quite good and they have grown at a similar rate, just starting to produce third leaves by March 2007. These have also suffered from calcium deposits from my fogging system, but again the effect seems to be purely cosmetic, although I would speculate that it may reduce photosynthesis potential and thus slow growth to some extent. The plants are looking quite leggy, probably due to excessive shade, although radicalis are well known for their low light tolerance, so they may adapt to this a little better with age. These plants are somewhat overdue re-potting and separation, as the roots will be more difficult to separate with time, although I will probably keep three or four plants to each larger pot, so it will hopefully be fairly easy to separate them into three small clusters.
