Fire-weed, Great Willow-herb
Chamaenèrion angustifòlium (Epilobium)
Purple, pink
Summer
Across the continent
A striking and decorative perennial, from two to six feet tall, with alternate leaves, pale on the under side, the veins making a scalloped border near the margin, the upper leaves and stems sometimes slightly downy, and the drooping buds deep reddish-pink or purple. The flowers form a fine cluster, with small bracts, each flower an inch or more across, the sepals often pink or purple and the petals bright purplish-pink; the stamens drooping, with purplish anthers; the style hairy at base, the capsule two or three inches long. This is very common, both East and West, reaching an altitude of ten thousand feet, and often growing in such quantities in the mountains as to cover large tracts with bright color. The seeds are furnished with tufts of white, silky hairs, making the plant very conspicuous when gone to seed, covering it with untidy bunches of pale down and giving a strange shaggy effect. It often flourishes in places that have been burned over, hence the name Fire-weed, and Willow-herb is from the leaves and the silky down on the seeds, suggestive of willows.
Water Willow-herb
Chamaenèrion latifòlium (Epilobium)
Magenta
Summer
Northwest
This grows in wet places; the flowers are larger and handsomer than the last, but it is not so tall. The stems are stout, reddish, and branching, from six to eighteen inches high, both stem and leaves with a "bloom," and the leaves are thickish, bluish-green on the upper side and paler yellowish-green on the under, sometimes toothed, with no veined border. The buds are deep-red and the flowers form a handsomer cluster, shorter than the last, with leafy bracts, each flower from one to over two inches across, with reddish-pink sepals, deep-red outside, and magenta petals veined with deeper color, sometimes notched, one petal longer than the others; the anthers purplish; the pistil drooping and purplish, with a smooth style. This plant is also covered with tufts of white down when gone to seed. The contrasting purples and reds of the flowers give a very vivid effect, set off by the bluish-green foliage, especially when growing among the gray rocks of moraines, watered by icy glacier streams. It reaches an altitude of ten thousand feet, growing in the East and in Europe and Asia.
Water Willow-herb—Chamaenerion latifolium.
Fire-weed—C. angustifolium.
There are many kinds of Epilobium, differing from Chamaenerion chiefly in the calyx-tube, which is prolonged beyond the ovary.
Willow Herb
Epilòbium Franciscànum
Pink
Spring
Northwest
A perennial, not especially pretty, with a stout, reddish stem, from one to three feet tall, slightly downy above, and dull green leaves, mostly smooth and the lower ones opposite. The flowers are less than half an inch across, with bright or pale, purplish-pink petals, deeply notched and not spreading. This grows in wet spots around San Francisco.
There are several kinds of Gayophytum; differing from Epilobium in the capsule and seeds, and easily distinguished from them by the hairy buds; leaves alternate, long, narrow, and toothless; flowers small; petals four, white or pink, with very short claws; stamens, with swinging anthers, eight, four shorter and usually sterile; capsule club-shaped. The species are difficult to distinguish, because of the smallness of the flowers.
