Wild Flowers Part 16

AMERICAN or GREAT RHODODENDRON; GREAT LAUREL; ROSE TREE, or BAY (Rhododendron maximum) Heath family

Flowers - Rose pink, varying to white, greenish in the throat, spotted with yellow or orange, in broad cl.u.s.ters set like a bouquet among leaves, and developed from scaly, cone-like buds; pedicels sticky-hairy. Calyx 5-parted, minute; corolla 5-lobed, broadly bell-shaped, 2 in. broad or less usually 10 stamens, equally spreading; pistil. Stem: Sometimes a tree attaining a height of 40 ft., usually 6 to 20 ft., shrubby, woody. Leaves: Evergreen, drooping in winter, leathery, dark green on both sides, lance-oblong, 4 to 10 in. long, entire edged, narrowing into stout petioles.

Preferred Habitat - Mountainous woodland, hillsides near streams.

Flowering Season - June-July.

Distribution - Uncommon from Ohio and New England to Nova Scotia; abundant through the Alleghanies to Georgia.

When this most magnificent of our native shrubs covers whole mountain sides throughout the Alleghany region with bloom, one stands awed in the presence of such overwhelming beauty. Nowhere else does the rhododendron attain such size or luxuriance. There it produces a tall trunk, and towers among the trees; it spreads its branches far and wide until they interlock and form almost impenetrable thickets locally called "h.e.l.ls;" it glorifies the loneliest mountain road with superb bouquets of its delicate flowers set among dark, glossy foliage scarcely less attractive.

The mountain in bloom is worth travelling a thousand miles to see.

Farther south the more purplish-pink or lilac-flowered CAROLINA RHODODENDRON (R. Catawbiense) flourishes. This southern shrub, which is perfectly hardy, unlike its northern sister, has been used by cultivators as a basis for producing the fine hybrids now so extensively grown on lawns in this country and Europe. Crossed with the Nepal species (R. arboreum) the best results follow.

Americans, ever too p.r.o.ne to make the eagle scream on their trips abroad, need not monopolize all the glory for the cultivated rhododendron, as they are apt to do when they see it on fine estates in England. The Himalayas, which are covered with rhododendrons of brighter hue than ours, furnish many of the shrubs of commerce. Our rhododendron produces one of the hardest and strongest of woods, weighing thirty-nine pounds per cubic foot.

Rhododendrons, azaleas, and laurels fall under a common ban p.r.o.nounced by bee-keepers. The bees which transfer pollen from blossom to blossom while gathering nectar, manufacture honey said to be poisonous. Cattle know enough to let all this foliage alone. Apparently the ants fear no more evil results from the nectar than the bees themselves; and were it not for the sticky parts nearest the flowers, on which they crawl to meet their death, the blossom's true benefactors would find little refreshment left.

MOUNTAIN or AMERICAN LAUREL; CALICO BUSH; SPOONWOOD; CALMOUN; BROAD-LEAVED KALMIA (Kalmia latifolia) Heath family

Flowers - Buds and new flowers bright rose pink, afterward fading white, and only lined with pink, 1 in. across, or less, numerous, in terminal cl.u.s.ters. Calyx small, 5-parted, sticky corolla like a 5-pointed saucer, with 10 projections on outside; 10 arching stamens, an anther lodged in each projection; 1 pistil. Stem: Shrubby, woody, stiffly branched, 2 to 20 ft. high. Leaves: Evergreen, entire, oval to elliptic, pointed at both ends, tapering into petioles. Fruit: A round, brown capsule, with the style long remaining on it.

Preferred Habitat - Sandy or rocky woods, especially in hilly or mountainous country.

Flowering Season - May-June.

Distribution - New Brunswick and Ontario, southward to the Gulf of Mexico, and westward to Ohio.

It would be well if Americans, imitating the j.a.panese in making pilgrimages to scenes of supreme natural beauty, visited the mountains, rocky, woody hillsides, ravines, and tree-girt uplands when the laurel is in its glory; when ma.s.ses of its pink and white blossoms, set among the dark evergreen leaves, flush the landscape like Aurora, and are reflected from the pools of streams and the serene depths of mountain lakes. Peter Kalm, a Swedish pupil of Linnaeus, who traveled here early in the eighteenth century, was more impressed by its beauty than that of any other flower. He introduced the plant to Europe, where it is known as kalmia, and extensively cultivated on fine estates that are thrown open to the public during the flowering season. Even a flower is not without honor, save in its own country. We have only to prepare a border of leaf-mould, take up the young plant without injuring the roots or allowing them to dry, hurry them into the ground, and prune back the bush a little, to establish it in our gardens, where it will bloom freely after the second year.

All the kalmias resort to a most ingenious device for compelling insect visitors to carry their pollen from blossom to blossom. A newly opened flower has its stigma erected where the incoming bee must leave on its sticky surface the four minute orange-like grains carried from the anther of another flower on the hairy underside of her body. Now, each anther is tucked away in one of the ten little pockets of the saucer-shaped blossom, and the elastic filaments are strained upward like a bow. After hovering above the nectary, the bee has only to descend toward it, when her leg, touching against one of the hair-triggers of the spring trap, pop goes the little anther-gun, discharging pollen from its bores as it flies upward. So delicately is the mechanism adjusted, the slightest jar or rough handling releases the anthers; but, on the other hand, should insects be excluded by a net stretched over the plant, the flowers will fall off and wither without firing off their pollen-charged guns. At least, this is true in the great majority of tests. As in the case of hothouse flowers no fertile seed is set when nets keep away the laurel's benefactors. One has only to touch the hair-trigger with the end of a pin to see how exquisitely delicate is this provision for cross-fertilization.

However much we may be cautioned by the apiculturalists against honey made from laurel nectar, the bees themselves ignore all warnings and apparently without evil results - happily for flowers dependent upon them and their kin. Mr. Frank R. Cheshire, in "Bees and Bee-keeping," the standard English work on the subject, writes: "During the celebrated Retreat of the Ten Thousand, as recorded by Xenophon in his 'Anabasis,' the soldiers regaled themselves upon some honey found near Trebizonde where were many beehives. Intoxication with vomiting was the result.

Some were so overcome, he states, as to be incapable of standing.

Not a soldier died, but very many were greatly weakened for several days. Tournefort endeavored to ascertain whether this account was corroborated by anything ascertainable in the locality, and had good reason to be satisfied respecting it. He concluded that the honey had been gathered from a shrub growing in the neighborhood of Trebizonde, which is well known there as producing the before-mentioned effects. It is now agreed that the plants were species of rhododendron and azaleas. Lamberti confirms Xenophon's account by stating that similar effects are produced by honey of Colchis, where the same shrubs are common.

In 1790, even, fatal cases occurred in America in consequence of eating wild honey, which was traced to Kahmia latifolia by an inquiry inst.i.tuted under direction of the American government.

Happily, our American cousins are now never likely to thus suffer, thanks to drainage, the plow, and the bee-farm."

One of the beautiful swallow-tail b.u.t.terflies lays its eggs on laurel leaves, that the larvae may feed on them later; yet the foliage often proves deadly to more highly organized creatures.

Most cattle know enough to let it alone; nevertheless some fall victims to it every year. Even the intelligent grouse, hard pressed with hunger when deep snow covers much of their chosen food are sometimes found dead and their crops distended by these leaves. How far more unkind than the bristly armored thistle's is the laurel's method of protecting itself against destruction!

Even the ant, intent on pilfering sweets secreted for bees, it ruthlessly glues to death against its sticky stems and calices.

According to Dr. Barton the Indians drink a decoction of kalmia leaves when they wish to commit suicide.

As laurel wood is very hard and solid, weighing forty-four pounds to the cubic foot, it is in great demand for various purposes, one of them indicated in the plant's popular name of Spoon-wood.

SHEEP-LAUREL, LAMB-KILL, WICKY, CALF-KILL, SHEEP-POISON NARROW-LEAVED LAUREL (K. angustifolia), and so on through a list of folk names testifying chiefly to the plant's wickedness in the pasture, may be especially deadly food for cattle, but it certainly is a feast to the eyes. However much we may admire the small, deep crimson-pink flowers that we find in June and July in moist fields or swampy ground or on the hillsides, few of us will agree with Th.o.r.eau, who claimed that it is "handsomer than the mountain laurel." The low shrub may be only six inches high, or it may attain three feet. The narrow evergreen leaves, pale on the underside, have a tendency to form groups of threes, standing upright when newly put forth, but bent downward with the weight of age. A peculiarity of the plant is that cl.u.s.ters of leaves usually terminate the woody stem, for the flowers grow in whorls or in cl.u.s.ters at the side of it below.

The PALE or SWAMP LAUREL (K. glauca), found in cool bogs from Newfoundland to New Jersey and Michigan, and westward to the Pacific Coast, coats the under side of its mostly upright leaves with a smooth whitish bloom like the cabbage's. It is a straggling little bush, even lower than the lamb-kill, and an earlier bloomer, putting forth its loose, n.i.g.g.ardly cl.u.s.ters of deep rose or lilac-colored flowers in June.

TRAILING ARBUTUS; MAYFLOWER; GROUND LAUREL (Epigaea repens) Heath family

Flowers - Pink, fading to nearly white, very fragrant about 1/2 in. across when expanded, few or many in cl.u.s.ters at ends of branches. Calyx of 5 dry overlapping sepals; corolla salver-shaped, the slender, hairy tube spreading into 5 equal lobes; 10 stamens; 1 pistil with a column-like style and a 5-lobed stigma. Stem: Spreading over the ground (Epigaea = on the earth); woody, the leafy twigs covered with rusty hairs. Leaves: Alternate, oval, rounded at the base, smooth above, more or less hairy below, evergreen, weather-worn, on short, rusty, hairy petioles.

Preferred Habitat - Light sandy loam in woods, especially under evergreen trees, or in mossy, rocky places.

Flowering Season - March-May.

Distribution - Newfoundland to Florida, west to Kentucky, and the Northwest Territory.

Can words describe the fragrance of the very breath of spring - that delicious commingling of the perfume of arbutus, the odor of pines, and the snow-soaked soil just warming into life? Those who know the flower only as it is sold in the city streets, tied with wet, dirty string into tight bunches, withered and forlorn, can have little idea of the joy of finding the pink, pearly blossoms freshly opened among the withered leaves of oak and chestnut, moss, and pine needles in which they nestle close to the cold earth in the leafless, windy northern forest. Even in Florida, where broad patches carpet the woods in February, one misses something of the arbutus's accustomed charm simply because there are no slushy remnants of snow drifts, no reminders of winter hardships in the vicinity. There can be no glad surprise at finding dainty spring flowers in a land of perpetual summer.

Little wonder that the Pilgrim Fathers, after the first awful winter on the "stern New England coast," loved this early messenger of hope and gladness above the frozen ground at Plymouth. In an introductory note to his poem "The Mayflowers,"

Whittier states that the name was familiar in England, as the application of it to the historic vessel shows; but it was applied by the English, and still is, to the hawthorn. Its use in New England in connection with the trailing arbutus dates from a very early day, some claiming that the first Pilgrims so used it in affectionate memory of the vessel and its English flower a.s.sociation.

"Sad Mayflower I watched by winter stars, And nursed by winter gales, With petals of the sleeted spars, And leaves of frozen sails!

"But warmer suns ere long shall bring To life the frozen sod, And through dead leaves of hope shall spring Afresh the flowers of G.o.d!"

Some have attempted to show that the Pilgrims did not find the flowers until the last month of spring, and that, therefore, they were named Mayflowers. Certainly the arbutus is not a typical May blossom even in New England. Bryant a.s.sociates it with the hepatica, our earliest spring flower, in his poem, "The, Twenty-seventh of March":

"Within the woods Tufts of ground laurel, creeping underneath The leaves of the last summer, send their sweets Upon the chilly air, and by the oak, The squirrel cups, a graceful company Hide in their bells a soft aerial blue."

There is little use trying to coax this shyest of sylvan flowers into our gardens where other members of its family, rhododendrons, laurels, and azaleas make themselves delightfully at home. It is wild as a hawk, an untamable creature that slowly pines to death when brought into contact with civilization.

Greedy street venders, who ruthlessly tear up the plant by the yard, and others without even the excuse of eking out a paltry income by its sale, have already exterminated it within a wide radius of our Eastern cities. How curious that the majority of people show their appreciation of a flower's beauty only by selfishly, ignorantly picking every specimen they can find!

In many localities the arbutus sets no fruit, for it is still undergoing evolutionary changes looking toward the perfecting of an elaborate system to insure cross-fertilization. Already it has attained to perfume, nectar, and color to attract quant.i.ties of insects, chiefly flies and small female bees but in some flowers the anthers produce no pollen for them to carry, while others are filled with grains, yet all the stigmas in the neighboring cl.u.s.ters may be defective. The styles and the filaments are of several different lengths, showing a tendency toward trimorphism, perhaps, like the wonderful purple loosestrife; but at present the flower pursues a most wasteful method of distributing pollen, and in different sections of the country acts so differently that its phases are impossible to describe except to the advanced student. They may, however, be best summarized in the words of Professor Asa Gray: "The flowers are of two kinds, each with two modifications; the two main kinds characterized by the nature and perfection of the stigma, along with more or less abortion of the stamens; their modifications by the length of the style."

When our English cousins speak of the arbutus, they have in mind a very different species from ours. Theirs is the late flowering strawberry-tree, an evergreen shrub with cl.u.s.tering white blossoms and beautiful rough, red berries. Indeed, the name arbutus is derived from the Celtic word Arboise, meaning rough fruit.

LARGE or AMERICAN CRANBERRY (Oxycoccus macrocarpus; Vaccinium macrocarpon of Gray) Huckleberry family

Flowers - Light pink, about 1/2 in. across, nodding on slender pedicels from sides and tips of erect branches. Calyx round, 4-or 5-parted; corolla a long cone in bud, its four or five nearly separate, narrow petals turned far backward later; 8 or 10 stamens, the anthers united into a protruding cone, its hollow tubes shedding pollen by a pore at tip. Stem: Creeping or trailing, slender, woody, 1 to 3 ft. long, its leafy branches 8 in. high or less. Leaves: Small, alternate, oblong, evergreen, pale beneath, the edges rolled backward. Fruit: An oblong or ovoid, many seeded, juicy red berry (Oxycoccus = sour berry).

Preferred Habitat - Bogs; sandy, swampy meadows.

Flowering Season - June-August.

Distribution - North Carolina, Michigan, and Minnesota northward and westward.

A hundred thousand people are interested in the berry of this pretty vine to one who has ever seen its flowers. Yet if the blossom were less attractive, to insects at least, and took less pains to shake out its pollen upon them as they cling to the cone to sip its nectar, few berries would accompany the festive Thanksgiving turkey. Cultivators of the cranberry know how important it is to have the flooded bogs well drained before the flowering season. Water (or ice) may cover the plants to the depth of a foot or more all winter and until the 10th of May; and during the late summer it is often advisable to overflow the bogs to prevent injury of the fine, delicate roots from drought, and to destroy the worm that is the plant's worst enemy; but until the flowers have wooed the bees, flies, and other winged benefactors, and fruit is well formed, every cultivator knows enough not to submerge his bog. With flowers under water there are no insect visitors, consequently no berries. Dense mats of the wiry vines should yield about one hundred and fifty bushels of berries to the acre, under skilful cultivation - a most profitable industry, since the cranberry costs less to cultivate, gather, and market than the strawberry or any of the small perishable fruits. Planted in muck and sand in the garden, the vines yield surprisingly good results. The Cape Cod Bell is the best known market berry. One of the interesting sights to the city loiterer about the New England coast in early autumn is the berry picking that is conducted on an immense scale. Men, women, and children drop all other work; whole villages are nearly depopulated while daylight lasts; temporary buildings set up on the edges of the bogs contain throngs of busy people sorting, measuring, and packing fruit; and lonely railroad stations, piled high with crates, give the branch line its heaviest freight business of the year.

SHOOTING STAR; AMERICAN COWSLIP; PRIDE OF OHIO (Dodecatheon Meadia) Primrose family

Flowers - Purplish pink or yellowish white, the cone tipped with yellow; few or numerous, hanging on slender, recurved pedicels in an umbel at top of a simple scape 6 in. to 2 ft. high. Calyx deeply 5-parted; corolla of 5 narrow lobes bent backward and upward; the tube very short, thickened at throat, and marked with dark reddish-purple dots; 5 stamens united into a protruding cone; 1 pistil, protruding beyond them. Leaves: Oblong or spatulate 3 to 12 in. long, narrowed into petioles, all from fibrous roots. Fruit: A 5-valved capsule on erect pedicels.

Preferred Habitat - Prairies, open woods, moist cliffs. Flowering Season - April-May.

Distribution - Pennsylvania southward and westward, and from Texas to Manitoba.

Ages ago Theophrastus called an entirely different plant by this same scientific name, derived from dodeka = twelve, and theos = G.o.ds; and although our plant is native of a land unknown to the ancients, the fanciful Linnaeus imagined he saw in the flowers of its umbel a little congress of their divinities seated around a miniature Olympus! Who has said science kills imagination? These handsome, interesting flowers so familiar in the Middle West and Southwest, especially, somewhat resemble the cyclamen in oddity of form, indeed, these prairie wildflowers are not unknown in florists' shops in Eastern cities.

Many flowers like the shooting star, cyclamen, and nightshade, with protruding cones made up of united stamens, are so designed that, as the bees must cling to them while sucking nectar, they receive pollen jarred out from the end of the cone on their undersides. The reflexed petals serve three purposes: First, in making the flower more conspicuous; secondly, in facilitating access to nectar and pollen; and, finally, in discouraging crawling intruders. Where the short tube is thickened, the bee finds her foothold while she forces her tongue between the anther tips. The nectar is well concealed and quite deeply seated, thanks to the rigid cone. Few bee workers are flying at the shooting star's early blooming season. Undoubtedly the female b.u.mblebees, which, by striking the protruding stigma before they jar out any pollen, cross-fertilize it, are the flower's benefactors; but one frequently sees the little yellow puddle b.u.t.terfly clinging to the pretty blossoms.

Very different from the bright yellow cowslip of Europe is our odd, misnamed blossom.

BITTER-BLOOM; ROSE-PINK; SQUARE-STEMMED SABBATIA; ROSY CENTAURY (Sabbatia angularis) Gentian family

Flowers - Clear rose pink, with greenish star in center, rarely white, fragrant, 1 1/2 in. broad or less, usually solitary on long peduncles at ends of branches. Calyx lobes very narrow; corolla of 5 rounded segments; stamens 5; style 2-cleft. Stem: Sharply 4-angled, 2 to 3 ft. high, with opposite branches, leafy.

Leaves: Opposite, 5-nerved, oval, tapering at tip, and clasping stem by broad base.
