Nepenthes burbidgeae 50% silica gel, 20% "Sphagnum" moss, 20% fir bark, and 10% peat moss chunks. The highest growth rates were exhibited by specimens in 50% leached perlite, 30% long fiber "Sphagnum" moss, 10% peat moss chunks, and 10% fir bark, as well as media without fir bark and with a higher percentage of "Sphagnum". "Nepenthes burbidgeae" was found to tolerate temperatures in the range of 9 to 41 °C (48° to 105 °F). A nighttime drop in temperature below 18 °C (65 °F) was necessary for good growth; plants that were not exposed to such a drop grew around 50% slower
Sphagnum cuspidatum branch leaves can sometimes be faintly serrated. "S. cuspidatum" is a dioecious species. The spores produced are 29-38 µm, covered with large papillae on both surfaces, and appear to be covered in small blisters (pusticulate). "S. cuspidatum" can be found on wet humus under forests and on the bases of trees forming a hummock-hollow complex; in or near bogs. Distinguishing "Sphagnum cuspidatum" from "Sphagnum viride" is sometimes difficult as both occur over a similar geographic range and both grow in wet carpets. "Sphagnum cuspidatum" has narrower branch leaves and usually a distinct red tinge at the branch bases within the
