Wild Flowers An Aid To Knowledge Of Our Wild Flowers And Their
Chapter 5
The merest novice can have no difficulty in naming the flower whose wild and cultivated relations abound throughout North America, the almost exclusive home of the genus, although it is to European horticulturists, as usual the first to see the possibilities in our native flowers, that we owe the gay hybrids in our gardens. Mr. Drummond, a collector from the Botanical Society of Glasgow, early in the thirties sent home the seeds of a species from Texas, which became the ancestor of the gorgeous annuals, the Drummond phloxes of commerce today; and although he died of fever in Cuba before the plants became generally known, not even his kinsman, the author of "Natural Law in the Spiritual World," has done more to immortalize the family name.
While the wild blue phlox is sometimes cultivated, it is the GARDEN PHLOX (P. paniculata), common in woods and thickets from Pennsylvania to Illinois and southward, that under a gardener's care bears the large terminal clusters of purple, magenta, crimson, pink, and white flowers abundant in old-fashioned, hardy borders. From these it has escaped so freely in many sections of the North and East as to be counted among the local wildflowers. Unless the young offshoots are separated from the parent and given a nook of their own, the flower quickly reverts to the original type. European cultivators claim that the most brilliant colors are obtained by crossing annual with perennial phloxes.
WILD SWEET WILLIAM (P. maculata), another perennial much sought by cultivators, loves the moisture of low woods and the neighborhood of streams in the Middle and Western States when it is free to choose its habitat; but it, too, has so freely escaped from gardens farther north into dry and dusty roadsides, that anyone who has passed the ruins of Hawthorne's little red cottage at Lenox, for example, and seen the way his wife's clump of white phlox under his study window has spread to cover an acre of hillside, would suppose it to be luxuriating in its favorite locality. This variety of the species (var. Candida) lacks the purplish flecks on stem and lower leaves responsible for the specific name of the type. Pinkish purple or pink blossoms are borne in a rather narrow, elongated panicle on the typical Sweet William.
Most members of the phlox family resort to the trick of coating the upper stem and the peduncles immediately below the flowers with a sticky secretion in which crawling insects, intent on pilfering sweets, meet their death, just as birds are caught on limed twigs. Butterflies, for whom phloxes have narrowed their tubes to the exclusion of most other insects, are their benefactors; but long-tongued bees and flies often seek their nectar. Indeed, the number of strictly butterfly-flowers is surprisingly small.
VIRGINIA COWSLIP; TREE or SMOOTH LUNGWORT; BLUE-BELLS (Mertensia Virginica) Borage family
Flowers - Pinkish in bud, afterward purplish blue, fading to light blue; about 1 in. long, tubular, funnel form, the tube of corolla not crested; spreading or hanging on slender pedicels in showy, loose clusters at end of smooth stem from 1 to 2 ft. high; stamens 5, inserted on corolla; 1 pistil; ovary of 4 divisions. Leaves: Large, entire, alternate, veiny, oblong or obovate, the upper ones seated on stem; lower very large ones diminishing toward base into long petioles; at first rich, dark purple, afterward pale bluish gray. Fruit: 4 seed-like little nuts, leathery, wrinkled when mature. Preferred Habitat - Alluvial ground, low meadows, and along streams. Flowering Season - March-May. Distribution - Southern Canada to South Carolina and Kansas, west to Nebraska; most abundant in middle West.
Not to be outdone by its cousins the heliotrope and the forget-me-not, this lovely and far more showy spring flower has found its way into the rockwork and sheltered, moist nooks of many gardens, especially in England, where Mr. W. Robinson, who has appealed for its wider cultivation in that perennially charming book, "The English Flower Garden," says of the Mertensias: "There is something about them more beautiful in form of foliage and stem, and in the graceful way in which they rise to panicles of blue, than in almost any other family.... Handsomest of all is the Virginia cowslip." And yet Robinson never saw the alluvial meadows in the Ohio Valley blued with lovely masses of the plant in April.
A great variety of insects visit this blossom, which, being tubular, conducts them straight to the ample feast; but not until they have deposited some pollen brought from another flower on the stigma in their way. The anthers are too widely separated from the stigma to make self-fertilization likely. Occasionally one finds the cowslips perforated by clever bumblebees. As only the females, which are able to sip far deeper cups, are flying when they bloom, they must be either too mischievous or too lazy to drain them in the legitimate manner. Butterflies have only to stand on a flower, not to enter it, in order to sip nectar from the four glands that secrete it abundantly.
FORGET-ME-NOT; MOUSE-EAR; SCORPION GRASS; SNAKE GRASS; LOVE ME (Myosotis Palustris) Borage family
Flowers - Pure blue, pinkish, or white, with yellow eye; flat, 5-lobed, borne in many-flowered, long, often 1-sided racemes. Calyx 5-cleft; the lobes narrow, spreading, erect, and open in fruit; 5 stamens inserted on corolla tube; style threadlike; ovary 4-celled. Stem: Low, branching, leafy, slender, hairy, partially reclining. Leaves: (Myosotis = mouse-ear) oblong, alternate, seated on stem, hairy. Fruit: Nutlets, angled and keeled on inner side. Preferred Habitat - Escaped from gardens to brooksides, marshes, and low meadows. Flowering Season - May-July. Distribution - Native of Europe and Asia, now rapidly spreading from Nova Scotia southward to New Jersey, Pennsylvania, and beyond.
How rare a color blue must have been originally among our flora is evident from the majority of blue and purple flowers that, although now abundant here and so perfectly at home, are really quite recent immigrants from Europe and Asia. But our dryer, hotter climate never brings to the perfection attained in England
"The sweet forget-me-nots That grow for happy lovers."
Tennyson thus ignores the melancholy association of the flower in the popular legend which tells how a lover, when trying to gather some of these blossoms for his sweetheart, fell into a deep pool, and threw a bunch on the bank, calling out, as he sank forever from her sight, "Forget me not." Another dismal myth sends its hero forth seeking hidden treasure caves in a mountain, under the guidance of a fairy. He fills his pockets with gold, but not heeding the fairy's warning to "forget not the best" - i.e., the myosotis - he is crushed by the closing together of the mountain. Happiest of all is the folk-tale of the Persians; as told by their poet Shiraz: "It was in the golden morning of the early world, when an angel sat weeping outside the closed gates of Paradise. He had fallen from his high estate through loving a daughter of earth, nor was he permitted to enter again until she whom he loved had planted the flowers of the forget-me-not in every corner of the world. He returned to earth and assisted her, and together they went hand in hand. When their task was ended, they entered Paradise together, for the fair woman, without tasting the bitterness of death, became immortal like the angel whose love her beauty had won when she sat by the river twining forget-me-nots in her hair."
It was the golden ring around the forget-me-not's center that first led Sprengel to believe the conspicuous markings at the entrance of many flowers served as pathfinders to insects. This golden circle also shelters the nectar from rain, and indicates to the fly or bee just where it must probe between stigma and anthers to touch them with opposite sides of its tongue. Since it may probe from any point of the circle, it is quite likely that the side of the tongue that touched a pollen-laden anther in one flower will touch the stigma in the next one visited, and so cross-fertilize it. But forget-me-nots are not wholly dependent on insects. When these fail, a fully mature flower is still able to set fertile seed by shedding its own pollen directly on the stigma.
The SMALLER FORGET-ME-NOT (M. laxa), formerly accounted a mere variety of palustris, but now defined as a distinct species, is a native, and therefore may serve to show how its European relative here will deteriorate in the dryer atmosphere of the New World. Its tiny turquoise flowers, borne on long stems from a very loose raceme, gleam above wet, muddy places from Newfoundland and Eastern Canada to Virginia and Tennessee.
Even smaller still are the blue or white flowers of the FIELD FORGET-ME-NOT, SCORPION GRASS, or MOUSE-EAR (M. arvenis), whose stems and leaves are covered with bristly hairs. It blooms from August to July in dry places, even on hillsides, an unusual locality in which to find a member of this moisture-loving clan. All the flowers remain long in bloom, continually forming new buds on a lengthening stem, and leaving behind little empty green calices.
VIPER'S BUGLOSS; BLUE-WEED; VIPER'S HERB or GRASS; SNAKE-FLOWER; BLUE-THISTLE (Echium vulgare) Borage family
Flowers - Bright blue, afterward reddish purple, pink in the bud, numerous, clustered on short, 1-sided, curved spikes rolled up at first, and straightening out as flowers expand. Calyx deeply 5-cleft; corolla 1 in. long or less, funnel form, the 5 lobes unequal, acute; 5 stamens inserted on corolla tube, the filaments spreading below, and united above into slender appendage, the anthers forming a cone. 1 pistil with 2 stigmas. Stem: 1 to 2 1/2 ft. high; bristly-hairy, erect, spotted. Leaves: Hairy, rough, oblong to lance-shaped, alternate, seated on stem, except at base of plant. Preferred Habitat - Dry fields, waste places; roadsides. Flowering Season - June-July. Distribution - New Brunswick to Virginia, westward to Nebraska; Europe and Asia.
In England, from whose gardens this plant escaped long ago, a war of extermination that has been waged against the vigorous, beautiful weed by the farmers has at last driven it to the extremity of the island, where a few stragglers about Penzance testify to the vanquishing of what must once have been a mighty army. From England a few refugees reached here in i683, no one knows how; but they proved to be the vanguard of an aggressive and victorious host that quickly overran our open, hospitable country, as if to give vent to revenge for long years of persecution at the hands of Europeans. "It is a fact that all our more pernicious weeds, like our vermin, are of Old-World origin," says.John Burroughs. "...Perhaps the most notable thing about them, when compared with our native species, is their persistence, not to say pugnacity. They fight for the soil; they plant colonies here and there, and will not be rooted out. Our native weeds are for the most part shy and harmless, and retreat before civilization.... We have hardly a weed we can call our own."
Years ago, when simple folk believed God had marked plants with some sign to indicate the special use for which each was intended, they regarded the spotted stem of the bugloss, and its seeds shaped like a serpent's head, as certain indications that the herb would cure snake bites. Indeed, the genus takes its name from Echis, the Greek for viper.
Because it is showy and offers accessible nectar, a great variety of insects visit the blue-weed; Muller alone observed sixty-seven species about it. We need no longer wonder at its fertility. Of the five stamens one remains in the tube, while the other four project and form a convenient alighting place for visitors, which necessarily dust their under sides with pollen as they enter; for the red anthers were already ripe when the flower opened. Then, however, the short, immature pistil was kept below. After the stamens have shed their pollen and there can be no longer danger of self-fertilization, it gradually elongates itself beyond the point occupied by them, and divides into two little horns whose stigmatic surfaces an incoming pollen-laden insect cannot well fail to strike against. Cross-pollination is so thoroughly secured in this case that the plant has completely lost the power of fertilizing itself. Unwelcome visitors like ants, which would pilfer nectar without rendering any useful service in return, are warded off by the bristly, hairy foliage. Several kinds of female bees seek the bugloss exclusively for food for their larvae as well as for themselves, sweeping up the abundant pollen with their abdominal brushes as they feast without effort.
BLUE VERVAIN; WILD HYSSOP; SIMPLER'S JOY (Verbena hastala) Vervain family
Flowers - Very small, purplish blue, in numerous slender, erect, compact spikes. Calyx 5-toothed; corolla tubular, unequally 5-lobed; 2 pairs of stamens; 1 pistil. Stem: 3 to 7 ft. high, rough, branched above, leafy, 4-sided. Leaves: Opposite, stemmed, lance-shaped, saw-edged, rough; lower ones lobed at base. Preferred Habitat - Moist meadows, roadsides, waste places. Flowering Season - June-September. Distribution - United States and Canada in almost every part.
Seeds below, a circle of insignificant purple-blue flowers in the center, and buds at the top of the vervain's slender spires do not produce a striking effect, yet this common plant certainly does not lack beauty. John Burroughs, ever ready to say a kindly, appreciative word for any weed, speaks of its drooping, knotted threads, that "make a pretty etching upon the winter snow." Bees, the vervain's benefactors, are usually seen clinging to the blooming spikes, and apparently sleep on them. Borrowing the name of simpler's joy from its European sister, the flower has also appropriated much of the tradition and folk-lore centered about that plant which herb-gatherers, or simplers, truly delighted to see, since none was once more salable.
EUROPEAN VERVAIN (V. officinalis) HERB-OF-THE-CROSS, BERBINE, HOLY-HERB, ENCHANTER'S PLANT, JUNO'S TEARS, PIGEON-GRASS, LIGHTNING PLANT, SIMPLER'S JOY, and so on through a long list of popular names for the most part testifying to the plant's virtue as a love-philter, bridal token, and general cure-all, has now become naturalized from the Old World on the Atlantic and Pacific Slopes; and is rapidly appropriating waste arid cultivated ground until, in many places, it is truly troublesome. In general habit like the blue vervain, its flowers are more purplish than blue, and are scattered, not crowded, along the spikes. The leaves are deeply, but less acutely, cut.
Ages before Christians ascribed healing virtues to the vervain - found growing on Mount Calvary, and therefore possessing every sort of miraculous power, according to the logic of simple peasant folk - the Druids had counted it among their sacred plants. "When the dog-star arose from unsunned spots" the priests gathered it. Did not Shakespeare's witches learn some of their uncanny rites from these reverend men of old? One is impressed with the striking similarity of many customs recorded of both. Two of the most frequently used ingredients in witches' cauldrons were the vervain and the rue. "The former probably derived its notoriety from the fact of its being sacred to Thor, an honor which marked it out, like other lightning plants, as peculiarly adapted for occult uses," says Mr. Thiselton Dyer in his "Folk-lore of Plants." "Although vervain, therefore, as the enchanter's plant, was gathered by witches to do mischief in their incantations, yet, as Aubrey says, it 'hinders witches from their will,' a circumstance to which Drayton further refers when he speaks of the vervain as ''gainst witchcraft much avayling.'" Now we understand why the children of Shakespeare's time hung vervain and dill with a horseshoe over the door.
In his eighth Eclogue, Virgil refers to vervain as a charm to recover lost love. Doubtless this was the verbena, the herba sacra employed in ancient Roman sacrifices, according to Pliny. In his day the bridal wreath was of verbena, gathered by the bride herself.
NARROW-LEAVED VERVAIN (V. angustifolia), like the blue vervain, has a densely crowded spike of tiny purple or blue flowers that quickly give place to seeds, but usually there is only one spike at the end of a branch. The leaves are narrow, lance-shaped, acute, saw-edged, rough. From Massachusetts and Florida westward to Minnesota and Arkansas one finds the plant blooming in dry fields from June to August, after the parsimonious manner of the vervain tribe.
It is curious that the vervain, or verbena, employed by brides for centuries as the emblem of chastity, should be one of the notorious botanical examples of a willful hybrid. Generally, the individuals of distinct species do not interbreed; but verbenas are often difficult to name correctly in every case because of their susceptibility to each other's pollen - the reason why the garden verbena may so easily be made to blossom forth into whatever hue the gardener wills. His plants have been obtained, for the most part, from the large-flowered verbena, the beautiful purple, blue, or white species of our Western States (V. Canadensis) crossed with brilliant-hued species imported from South America.
MAD-DOG SKULLCAP or HELMET-FLOWER; MAD-WEED; HOODWORT (Scutellaria lateriflora) Mint family
Flowers - Blue, varying to whitish; several or many, 1/4 in. long, growing in axils of upper leaves or in 1-sided spike-like racemes. Calyx 2-lipped, the upper lip with a helmet-like protuberance; corolla 2-lipped; the lower, 3-lobed lip spreading; the middle lobe larger than the side ones. Stamens, 4, in pairs, under the upper lip; upper pair the shorter; one pistil, the style unequally cleft in two. Stem: Square, smooth, leafy, branched, 8 in. to 2 ft. high. Leaves: Opposite, oblong to lance-shaped, thin, toothed, on slender pedicles, 1 to 3 in. long, growing gradually smaller toward top of stem. Fruit: 4 nutlets. Preferred Habitat - Wet, shady ground. Flowering Season - July-September. Distribution - Uneven throughout United States and the British Possessions.
By the helmet-like appendage on the upper lip of the calyx, which to the imaginative mind of Linnaeus suggested Scutellum (a little dish), which children delight to spring open for a view of the four tiny seeds attached at the base when in fruit, one knows this to be a member of the skullcap tribe, a widely scattered genus of blue and violet two-lipped flowers, some small to the point of insignificance, like the present species, others showy enough for the garden, but all rich in nectar, and eagerly sought by bees. The wide middle lobe of the lower lip forms a convenient platform on which to alight; the stamens in the roof of a newly opened blossom dust the back of the visitor as he explores the nectary; and as the stamens of an older flower wither when they have shed their pollen, and the style then rises to occupy their position, it follows that, in flying from the top of one spike of flowers to the bottom of another, where the older ones are, the visitor, for whom the whole scheme of color, form, and arrangement was planned, deposits on the sticky top of the style some of the pollen he has brought with him and so cross-fertilizes the flower. When the seeds begin to form and the now useless corolla drops off, the helmet-like appendage on the top of the calyx enlarges and meets the lower lip, so enclosing and protecting the tiny nutlets. After their maturity, either the mouth gapes from dryness, or the appendage drops off altogether, from the same cause, to release the seeds. Old herb doctors, who professed to cure hydrophobia with this species, are responsible for its English misnomer.
Perhaps the most beautiful member of the genus is the SHOWY SKULLCAP (S. serrata), whose blue corolla, an inch long, has its narrow upper lip shorter than the spreading lower one. The flowers are set opposite each other at the end of the smooth stem, which rises from one to two feet high in the woods throughout a southerly and westerly range. As several other skullcaps have distinctly saw-edged leaves, this plant might have been given a more distinctive adjective, thinks one who did not have the naming of 200,000 species!
Above dry, sandy soil from New York and Michigan southward the HAIRY SKULLCAP (S. pilosa) lifts short racemes of blue flowers that are only half an inch long, and whose lower lip and lobes at either side are shorter than the arched upper lip. Most parts of the plant are covered with down, the lower stem being especially hairy; and this fact determines the species when connected with its rather distant pairs of indented, veiny leaves, ranging from oblong to egg-shaped, and furnished with petioles which grow gradually shorter toward the top, where pairs of bracts, seated on the stem, part to let the flowers spring from their axils.
The LARGER or HYSSOP SKULLCAP (S. integrifolia) rarely has a dent in its rounded oblong leaves ,which, like the stem, are covered with fine down. Its lovely, bright blue flowers, an inch long, the lips of about equal length, are grouped opposite each other at the top of a stem that never lifts them higher than two feet; and so their beauty is often concealed in the tall grass of roadsides and meadows and the undergrowth of woods and thickets, where they bloom from May to August, from southern New England to the Gulf of Mexico, westward to Texas.
This tribe of plants is almost exclusively North American, but the hardy MARSH SKULLCAP or HOODED WILLOW-HERB (S. galericulata), at least, roams over Europe, and Asia also, with the help of runners, as well as seeds that, sinking into the soft earth of swamps and the borders of brooks, find growth easy. The blue flowers which grow singly in the axils of the upper leaves are quite as long as those of the larger and the showy skullcaps; the oblong, lance-shaped leaves, which are mostly seated on the branching stem, opposite each other, have low teeth. Why do leaves vary as they do, especially in closely allied species? "The causes which have led to the different forms of leaves have been, so far as I know," says Sir John Lubbock, "explained in very few cases: those of the shapes and structure of seeds are tolerably obvious in some species, but in the majority they are still entirely unexplained; and, even as regards the blossoms themselves, in spite of the numerous and conscientious labors of so many eminent naturalists, there is as yet no single species thoroughly known to us."
GROUND IVY or JOY; GILL-OVER-THE-GROUND; FIELD BALM; CREEPING CHARLIE (Glecoma hederacea; Nepeta Glechoma of Gray) Mint family
