WILD FLOWERS [219]

a composite that has once taken possession of their fields.

Blazing hot sunny fields, in which black-eyed Susan feels most comfortable, suit the TALL or GREEN-HEADED CONE-FLOWER OR THIMBLEWEED (R. laciniata) not at all. Its preference is for moist thickets such as border swamps and meadow runnels. Consequently it has no need of the bristly-hairy coat that screens the yellow daisy from too tierce, sunlight, and great need of more branches and leaves. (See prickly pear.) This is a smooth, much branched plant, towering sometimes twelve feet high, though commonly not even half that height; its great lower leaves, on long petioles, have from three to seven divisions variously lobed and toothed; while the stem leaves are irregularly three to five parted or divided. The numerous showy heads, which measure from two and a half to four inches across, have from six to ten bright yellow rays drooping a trifle around a dull greenish-yellow conical disk that gradually lengthens to twice its breadth, if not more, as the seeds mature. July-September, Quebec to Montana, and southward to the Gulf of Mexico.


TALL or GIANT SUNFLOWER (Heliainthus giganteus) Thistle family

Flower-heads - Several, on long, rough-hairy peduncles; 1 1/2 to 2 1/4 in. broad; 10 to 20 pale yellow neutral rays around a yellowish disk whose florets are perfect, fertile. Stem: 3 to 12 ft. tall, bristly-hairy, usually branching above, often reddish from a perennial, fleshy root. Leaves: Rough, firm, lance-shaped, saw-toothed, sessile. Preferred Habitat - Low ground, wet meadows, swamps. Flowering Season - August-October. Distribution - Maine to Nebraska and the Northwest Territory, south to the Gulf of Mexico.

To how many sun-shaped golden disks with outflashing rays might not the generic name of this clan (helios = the sun, anthos = a flower) be as fittingly applied: from midsummer till frost the earth seems given up to floral counterparts of his worshipful majesty. If, as we are told, one-ninth of all flowering plants in the world belong to the composite order, of which over sixteen hundred species are found in North America north of Mexico, surely over half this number are made up after the daisy pattern (q.v.), the most successful arrangement known, and the majority of these are wholly or partly yellow. Most conspicuous of the horde are the sunflowers, albeit they never reach in the wild state the gigantic dimensions and weight that cultivated, dark brown centered varieties produced from the COMMON SUNFLOWER (H. annus) have attained. For many years the origin of the latter flower, which suddenly shone forth in European gardens with unwonted splendor, was in doubt. Only lately. it was learned that when Champlain and Segur visited the Indians on Lake Huron's eastern shores about three centuries ago, they saw them cultivating this plant, which must have been brought by them from its native prairies beyond the Mississippi - a plant whose stalks furnished them with a textile fiber, its leaves fodder, its flowers a yellow dye, and its seeds, most valuable of all, food and hair oil. Early settlers in Canada were not slow in sending home to Europe so decorative and useful an acquisition. Swine, poultry, and parrots were fed on its rich seeds. Its flowers, even under Indian cultivation had already reached abnormal size. Of the sixty varied and interesting species of wild sunflowers known to scientists, all are North American. Moore's pretty statement,

"As the sunflower turns on her god when he sets The same look which she turn'd when he rose,"

lacks only truth to make it fact. The flower does not travel daily on its stalk from east to west. Often the top of the stem turns sharply toward the light to give the leaves better exposure, but the presence or absence of a terminal flower affects its action not at all.

Formerly the garden species was thought to be a native, not of our prairies, but of Mexico and Peru, because the Spanish conquerors found it employed there as a mystic and sacred symbol, much as the Egyptians employed the lotus in
