On the east side, however, where its "dark brow" overlooks the Red Tarn, and throws out two great lateral ridges--on the right, in De Quincey's words, "the awful curtain of rock called Striding Edge," and Swirrel Edge on the left--Helvellyn is a very fine mountain, and what is more to the present purpose, is botanically the most interesting of all the Lakeland fells. From Grisedale Tarn to Keppelcove, a distance of full three miles, that great escarpment, with the several "coves" that nestle beneath it, is the home of many rare Alpine flowers, corresponding in that respect with the Welsh rock-faces of Idwal and Cwm Glas; and though it does not offer so conspicuous a display, or such keen inducements to flower-gazing, a search along its narrow ledges, and under the impending crags, home of the hill fox, will seldom disappoint the adventurer. Some years ago I spent a week of July, in two successive seasons, at Patterdale, for the purpose of becoming better acquainted with the mountain flowers, but on both occasions the weather was very stormy and made it difficult to be on the fells. At first I searched chiefly under Striding Edge and the steep front of Helvellyn, among the rocks that lie behind the Red Tarn, and in similar places above Keppelcove Tarn in the adjoining valley, hoping with good luck to light on the snow-saxifrage. In this I was unsuccessful; but I twice found a plant I had not hitherto met with--in appearance a small spineless thistle, with a cluster of light-purple scented flowers--which proved to be the Alpine saw-wort, or _Saussurea_, and which in later years I saw again on Snowdon. A blossom which I picked and kept for several months was so little affected by its separation from the parent stem that it continued its vital processes in a vase, and passed from flowering to seeding without interruption. Like the orpine, it was a veritable "live-long," or as the politicians say, "die-hard." At Patterdale I was so fortunate as to make the acquaintance of Mr. Robert Nixon, a resident who has had a long and intimate knowledge of the local flora; and he very kindly devoted a day to showing me some of his flower-haunts on Helvellyn. In the course of this expedition, one of the pleasantest in my memory, a number of interesting plants were noted by us: among them the mountain-pansy; the cross-leaved bedstraw; the vernal sandwort; the Alpine meadow-rue; the moss-campion; the purple saxifrage, now past flowering; the mountain willow-herb (_epilobium alsinifolium_), not the true Alpine willow-herb, but a native of similar places among the higher rills; and the _salix herbacea_, or "least willow," the smallest of British trees, which when growing on the bare hill-tops is not more than two inches in height, though in the clefts of rock at the edge of the main escarpment we found it of much larger size.
