(Eupatorium perfoliatum) Thistle family
Flower-heads - Composite, the numerous, small, dull, white heads
of tubular florets only, crowded in a scaly involucre and borne
in spreading, flat-topped terminal cymes. Stem: Stout, tall,
branching above, hairy, leafy. Leaves: Opposite, often united at
their bases, or
clasping, lance-shaped, saw-edged, wrinkled.
Preferred Habitat - Wet ground, low meadows, roadsides.
Flowering Season - July-September.
Distribution - From the Gulf States north to Nebraska, Manitoba,
and New Brunswick.
Frequently, in just such situations as its sister the Joe-Pye
weed selects (q.v.), and with similar intent, the boneset spreads
its soft, leaden-white bloom; but it will be noticed that the
butterflies, which love color, especially deep pinks and magenta,
let this plant alone, whereas beetles, that do not find the
butterfly's favorite, fragrant Joe-Pye weed at all to their
liking, prefer these dull, odorous flowers. Many flies, wasps,
and bees also, get generous entertainment in these tiny florets,
where they feast with the minimum loss of time, each head in a
cluster containing, as it does, from ten to sixteen restaurants.
An ant crawling up the stem is usually discouraged by its hairs
long before reaching the sweets. Sometimes the stem appears to
run through the center of one large leaf that is kinky in the
middle and taper-pointed at both ends, rather than between a pair
of leaves.
An old-fashioned illness known as break-bone fever - doubtless
paralleled to-day by the grippe - once had its terrors for a
patient increased a hundredfold by the certainty he felt of
taking nauseous doses of boneset tea, administered by zealous old
women outside the "regular practice." Children who had to have
their noses held before they would - or, indeed, could - swallow
the decoction, cheerfully munched boneset taffy instead.
The bright white, wide-spread inflorescence of the WHITE
SNAKEROOT, WHITE or INDIAN SANICLE, or DEERWORT BONESET (E.
ageratoides) is displayed from July to November in the hope of
getting relief from the fiercest competition for the visits of
butterflies, honey and other small bees, wasps, and flies. From
July to September the vast army of composites appear in such
hopeless predominance that prolonged bloom on the part of any of
their number is surely an advantage. In the rich, moist woods, or
by shady roadsides, where it prefers to dwell, the white sanicle
makes a fine show. Above its fringy bloom how often one sees the
exquisite little lavender-blue butterflies (Lycaena
pseudargiolus) pausing an instant to drain the tiny cups of
nectar, and usually transferring pollen from the protruding
styles (q.v.) as they flit to another cluster.
The opposite, petioled leaves, broadly oval at the base,
taper-pointed, coarsely toothed, three-nerved, and veiny, are
thin and easily skeletonized by the insects that enjoy the leaves
of all this clan of plants. From one to four feet high, the White
Snakeroot grows in the United States and Canada as far west as
Nebraska.
Closely allied to the eupatoriums, and with similar
inflorescence, is the CLIMBING BONESET or HEMPWEED (Willughbaeaa
scandens; Mikania scandens of Gray.) Straggling over bushes in
swamps, by the brookside thicket, or in moist, shady roadsides,
the vine reveals its kinship to the boneset instantly it comes
into bloom in midsummer, although its flower clusters are
occasionally pinkish. The opposite, petioled leaves are quite
different from the boneset's, however, being heart-shaped at the
base, and taper-pointed, somewhat triangular, two to four inches
long, and one or two inches wide. From Massachusetts and the
Middle States even to South America and the West Indies is its
range.
WHITE ASTERS or STARWORTS
(Aster = a star) Thistle family
In dry, open woodlands, thickets, and roadsides, from August to
October, we find the dainty WHITE WOOD ASTER (A. divaricatus; A.
corymbosus of Gray) its brittle zig-zag stem two feet high or
less, branching at the top, and repeatedly forked where loose
clusters of flower-heads spread in a broad, rather flat corymb.
Only a few white rays - usually from six to nine - surround the
yellow disk, whose forets soon turn brown. Range from Canada
southward to Tennessee.
First to bloom among the white species, beginning in July, is the
UPLAND WHITE ASTER (A. ptarmicoides), which elects to grow in the
rocky or dry soil of high ground in the northern United States
westward to Colorado. The leaves, which resemble grayish-green
shining grass-blades, arranged alternately up the rigid stem, and
diminishing in size near the top until they become mere bracts
among the flowers, enable us to name the plant. The heads, in a
branching cluster, are not numerous; each measures barely an inch
across its ten to twenty snow-white rays; the center is of a pale
yellow-green, turning a light brown in maturity.
The TALL WHITE or PANICLED ASTER (A. paniculatus), in bloom from
August to October in different parts of its wide range, attracts
great numbers of beetles, which do it more harm than good; but
many more butterflies (some of whose caterpillars feed on aster
foliage as a staple), quantities of flies, some moths, swarms of
bees, wasps, and miscellaneous winged visitors. Professor
Robertson found several thousand callers, representing
ninety-eight distinct species, on this one aster during four
October days. Such popularity as the asters have attained finds
its just reward in the triumphant progress of the lovely tribe
(q.v.). For the amateur to name each member of such a horde is
quite hopeless. In branching, raceme-like clusters, from August
to October, this aster displays its numerous flower-heads, less
than an inch across, each with a green cup formed of four or five
series of overlapping bracts, and many white rays, occasionally
violet tipped. The smooth stem, which rises from two to eight
feet above moist soil, is plentifully set with alternate,
pointed-tipped, lance-shaped leaves, tapering to a sessile or
partly clasping base, and sparingly saw-edged. Its range is from
Montana east to Virginia, south to Louisiana, north to Ontario
and New England.
The bushy little WHITE HEATH ASTER (A. ericoides) every one must
know, possibly, as MICHAELMAS DAISY, FAREWELL SUMMER, WHITE
ROSEMARY, or FROSTWEED; for none is commoner in dry soil,
throughout the eastern United States at least. Its smooth, much
branched stem rarely reaches three feet in height, usually it is
not over a foot tall, and its very numerous flower-heads, white
or pink tinged, barely half an inch across, appear in such
profusion from September even to December as to transform it into
a feathery mass of bloom.
Growing like branching wands of golden rod, the DENSE-FLOWERED,
WHITE-WREATHED, or STARRY ASTER (A. multiflorus) bears its minute
flower-heads crowded close along the branches, where many small,
stiff leaves, like miniature pine needles, follow them. Each
flower measures only about a quarter of an inch across. From
Maine to Georgia and Texas westward to Arizona and British
Columbia the common bushy plant lifts its rather erect, curving,
feathery branches perhaps only a foot, sometimes above a man's
head, from August till November, in such dry, open, sterile
ground as the white heath aster also chooses.
No one not a latter-day, structural botanist could see why the
TALL, FLAT-TOP WHITE ASTER (Doellingeria umbella) is now an
outcast from the aster tribe into a separate genus. This common
species of moist soil and swamps has its numerous small heads
(containing ten to fifteen rays each) arranged in large,
terminal, compound clusters (corymbs). The stem, which rises from
two to eight feet, has its long-tapering, alternate leaves, hairy
on the veins beneath and rough margined.
Late in the fall you may hear the rich tone of a Bombilius, one
of the commonest flies seen about flowers, as he darts rapidly
among the white asters. Unless you have been initiated, you may
mistake this fly for a bee. He sings a very similar song and
wears a similar dress; but he is not a very good imitation, after
all, and a little familiarity with him will give you courage to
catch him in your hand if you are quick enough, for he is
incapable of stinging or biting: he can merely make a noise out
of all proportion to his size. He is simply living from hour to
hour, and lays up no store for the winter, enjoying more or less
security from his resemblance to the industrious and dangerous
insect which he imitates.
