In the novel this little bush features a lot. From the distance it looks like sheep on the hillside. Cushion-like white masses grow up to 60cm high by 2m long and 1m across. Its branchlets are so tightly packed it is impossible to part them. The interior of the plants contain a dense peaty mass of branchlets with old leaves. Amazingly, during winter the plant may be covered by several metres of snow, whilst in summer it will be baked during the day and blanketed in frost at night. A very cool plant indeed.
