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
Lough Derravaragh south of this raised bog. Much of the high bog possesses vegetation typical of an Irish Midland raised bog, with such species as ling heather ("Calluna vulgaris") and hare's tail cottongrass ("Eriophorum vaginatum"). The hummock-forming bog moss, "Sphagnum papillosum" has been recorded situated around one third of the high bog as has the more scarce "Sphagnum imbricatum". Overall, sphagnum covers around one-third of the high bog area. The centre of the bog is wet with stagnant water in places. The aquatic bog moss "Sphagnum cuspidatum" has been recorded in the hollows of the bog. There are dried-out channels of the
