Individual flower is a rosy, 5-point, star about ⅜ inch across, at the center of which is a group of 5 small appendages curving inward and forming a crown around the style and stamens. Numerous flowers cluster together into a ball about 3 inches in diameter. Plants are about 3 feet tall with thick broad leaves, the flower clusters borne at the top of the stem and in axils of upper leaves. Grows on plains, especially along ditch banks. Blooms June-July.
The common weeds are too often taken for granted and not appraised for their real beauty. This milkweed is in such a group—a coarse-growing plant along country roads, often dust covered, yet with flowers of fine delicate color and real charm whether we examine them singly or fix our attention on the compact cluster in which they grow. As autumn comes the dry leaves do not drop, but cling to the stem, rattling in the wind. The rough seed pods, often four inches long, turn a rich brown, and finally split open revealing a filling of lustrous, silky, down from which is gradually released the seeds—brown-clad paratroopers with the most airy-fairy parachutes in the world.
Morning-glory Family
Bush Morning-glory, Ipomoea leptophylla, TORR.
The flowers, shaped like pink trumpets with maroon striations, 3 inches long and 2 inches across the mouth, are scattered freely along the outer third of the stout yellowish stems which form a thick bush 2 feet or more high. New buds coming out each day keep the plant in bloom for the morning hours of several weeks. Leaves are narrow and linear, 2 inches long; the root is large and spongy. Grows in sandy soil on plains. Blooms July.
This morning-glory is no clinging vine, even though its flowers—like those of its cultivated relative on the back yard fence—do open only in the coolness of dawn and wither in the heat of noon. For all the sturdiness of individual plants, with their roots going “clear to China,” they do not seem to multiply rapidly and colonies of them may be miles apart. There are some fine bushes on the sandy hills along the Denver-Parker road, but the colony is becoming smaller rather than expanding. The common bindweed, Convolvulus arvenis, is a member of this same family. Its ability to spread rapidly along roads and into cultivated fields makes it a serious pest.
Waterleaf Family
Purple Fringe, Phacelia sericea, GRAY
Numerous purple flowers, each ¼ inch in diameter, crowd at and near the top of an erect hairy stem, making a cylindrical flower spike 3 inches or more in length. The 5 stamens of each flower are tipped with bright golden anthers and stick out farther than the petals, giving the effect of gold-headed pins radiating from a purple cushion. Plant is 6 to 12 inches tall of several leafy stems from a woody crown, the leaves divided into numerous narrow lobes. Grows in rather dry soil, montane to sub-alpine zones. Blooms May-July.
Many other species of Phacelia live in desert places where we have learned to know and admire them, but our first acquaintance—and last love—is this purple fringe of the montane zone. Its color is deeper, more velvety, and the pollen of its anthers brighter gold than most of its desert brethren can boast. It keeps, however, considerable tolerance for dry places, so that fresh road-fills are gay with it. The mountaineer who views his flowers only from a car has no excuse for not knowing this one.
