“Gathered upon a Friday, in the hour of Jupiter when he comes to his operation, so gathered, or borne, or hung upon the neck, it mightily helps to drive away all phantastical spirits.” These are the blossoms which have been hung in the windows of European peasants for ages on St. John’s eve, to avert the evil eye and the spells of the spirits of darkness. “Devil chaser” its Italian name signifies. To cure demoniacs, to ward off destruction by lightning, to reveal the presence of witches, and to expose their nefarious practices, are some of the virtues ascribed to this plant, which superstitious farmers have spared from the scythe and encouraged to grow near their houses until it has become, even in this land of liberty, a troublesome weed at times. “The flower gets its name,” says F. Schuyler Mathews, “from the superstition that on St. John’s day, the 24th of June, the dew which fell on the plant the evening before was efficacious in preserving the eyes from disease. So the plant was collected, dipped in oil, and thus transformed into a balm for every wound.” Here it is a naturalized immigrant, not a native. A blooming plant, usually with many sterile shoots about its base, has an unkempt, untidy look; the seed capsules and the brown petals of withered flowers remaining among the bright yellow buds through a long season.

The Shrubby St. John’s-wort (H. prolificum) bears yellow blossoms, about half an inch across, which are provided with stamens so numerous, the many flowered terminal clusters have a soft, feathery effect. In the axils of the oblong, opposite leaves are tufts of smaller ones, the stout stems being often concealed under a wealth of foliage. Sandy or rocky places from New Jersey southward best suit this low, dense, diffusely branched shrub which blooms prolifically from July to September.

Farther north, and westward to Iowa, the Great or Giant St. John’s-wort (H. Ascyron) brightens the banks of streams at midsummer with large blossoms, each on a long footstalk in a few-flowered cluster.

ROCKROSE FAMILY (Cistaceae)

Long-branched Frost-weed; Frost-flower; Frost-wort; Canadian Rockrose

Helianthemum canadense

Flowers--Solitary, or rarely 2; about 1 in. across, 5-parted, with showy yellow petals; the 5 unequal sepals hairy. Also abundant small flowers lacking petals, produced from the axils later. Stem: Erect, 3 in. to 2 ft. high; at first simple, later with elongated branches. Leaves: Alternate, oblong, almost seated on stem.

Preferred Habitat--Dry fields, sandy or rocky soil.

Flowering Season--Petal-bearing flowers, May-July.

Distribution--New England to the Carolinas, westward to Wisconsin and Kentucky.

When the stubble in the dry fields is white some cold November morning, comparatively few notice the ice crystals, like specks of glistening quartz, at the base of the stems of this plant. The similar Hoary Frost-weed (H. majus), whose showy flowers appear in clusters at the hoary stem’s summit in June and July, also bears them. Often this ice formation assumes exquisite feathery, whimsical forms, bursting the bark asunder where an astonishing quantity of sap gushes forth and freezes. Indeed, so much sap sometimes goes to the making of this crystal flower, that it would seem as if an extra reservoir in the soil must pump some up to supply it with its large fantastic corolla.

VIOLET FAMILY (Violaceae)

Blue and Purple Violets

Lacking perfume only to be a perfectly satisfying flower, the Common Purple, Meadow, or Hooded Blue Violet (V. cucullata) has nevertheless established itself in the hearts of the people from the Arctic to the Gulf as no sweet-scented, showy, hothouse exotic has ever done. Royal in color as in lavish profusion, it blossoms everywhere--in woods, waysides, meadows, and marshes, but always in finer form in cool, shady dells; with longer flowering scapes in meadow bogs; and with longer leaves than wide in swampy woodlands. The heart-shaped, saw-edged leaves, folded toward the centre when newly put forth, and the five-petalled, bluish-purple, golden-hearted blossom are too familiar for more detailed description. From the three-cornered stars of the elastic capsules, the seeds are scattered abroad.

In shale and sandy soil, even in the gravel of hillsides, one finds the narrowly divided, finely cut leaves and the bicolored beardless blossom of the Bird’s-foot Violet (V. pedata), pale bluish purple on the lower petals, dark purple on one or two upper ones, and with a heart of gold. The large, velvety, pansy-like blossom and the unusual foliage which rises in rather dense tufts are sufficient to distinguish the plant from its numerous kin. This species produces no cleistogamous or blind flowers. Frequently the Bird’s-foot Violet blooms a second time, in autumn, a delightful eccentricity of this family. The spur of its lower petal is long and very slender, and, as might be expected, the longest-tongued bees and butterflies are its most frequent visitors. These receive the pollen on the base of the proboscis.

In course of time the lovely English, March, or Sweet Violet (V. odorata), which has escaped from gardens, and which is now rapidly increasing with the help of seed and runners on the Atlantic and the Pacific coasts, may be established among our wild flowers. No blossom figures so prominently in European literature. In France, it has even entered the political field since Napoleon’s day. Yale University has adopted the violet for its own especial flower, although it is the corn-flower, or bachelor’s button (Centaurea cyanus) that is the true Yale blue. Sprengel, who made a most elaborate study of the violet, condensed the result of his research into the following questions and answers, which are given here because much that he says applies to our own native species, which have been too little studied in the modern scientific spirit:

“1. Why is the flower situated on a long stalk which is upright, but curved downward at the free end? In order that it may hang down; which, firstly, prevents rain from obtaining access to the nectar; and, secondly, places the stamens in such a position that the pollen falls into the open space between the pistil and the free ends of the stamens. If the flower were upright, the pollen would fall into the space between the base of the stamen and the base of the pistil, and would not come in contact with the bee.

“2. Why does the pollen differ from that of most other insect-fertilized flowers? In most of such flowers the insects themselves remove the pollen from the anthers, and it is therefore important that the pollen should not easily be detached and carried away by the wind. In the present case, on the contrary, it is desirable that it should be looser and drier, so that it may easily fall into the space between the stamens and the pistil. If it remained attached to the anther, it would not be touched by the bee, and the flower would remain unfertilized.

“3. Why is the base of the style so thin? In order that the bee may be more easily able to bend the style.

“4. Why is the base of the style bent? For the same reason. The result of the curvature is that the pistil is much more easily bent than would be the case if the style were straight.

“5. Finally, why does the membranous termination of the upper filament overlap the corresponding portions of the two middle stamens? Because this enables the bee to move the pistil and thereby to set free the pollen more easily than would be the case under the reverse arrangement.”

Yellow Violets

Fine hairs on the erect, leafy, usually single stem of the Downy Yellow Violet (V. pubescens), whose dark veined, bright yellow petals gleam in dry woods in April and May, easily distinguish it from the Smooth Yellow Violet (V. scabriuscula), formerly considered a mere variety in spite of its being an earlier bloomer, a lover of moisture, and well equipped with basal leaves at flowering time, which the downy species is not. Moreover, it bears a paler blossom, more coarsely dentate leaves, often decidedly taper-pointed, and usually several stems together.

Bryant, whose botanical lore did not always keep step with his Muse, wrote of the Yellow Violet as the first spring flower, because he found it “by the snowbank’s edges cold,” one April day, when the hepaticas about his home at Roslyn, Long Island, had doubtless been in bloom a month.
