THE DOGWOODS
According to Christian legends the Flowering Dogwood was used to make Jesus' cross because, at that time, it grew as large and sturdy as an oak. During the crucifixion, sensing the dogwood's sadness at being put to such a cruel use, He promised that henceforth, it shall be slender, bent and twisted; never again to be used for a cross.

Easter and spring both stand for the coming of new life. Our floral parade begins early with the bizarre fleshy bloom of the skunk cabbage and reaches a peak in early May. However, the flowering dogwood is lacking. It is native throughout most of the eastern half of the United States, but Chicago people must take week-end trips to downstate Illinois or Indiana to see it in bloom. There, on slopes and in woodlands, beneath the still leafless taller trees, its blossoms will flush the landscape like an untimely May snowstorm. A single one of its showy blooms is a dense head of tiny greenish flowers set in a white flower-like cup. What appear to be four broad petals with puckered notches at their tips are not true petals at all but the greatly expanded scales of the winter flower buds. In some of the eastern and southern states these may be pink or rose-colored.

This dogwood has up-tilted twigs tipped with two types of buds -- all delicately tinged with lavender, olive, purple and red. The flower buds are plump and globular while the leaf buds are slim. The oval leaves, rich green above and pale beneath, turn to glowing scarlet and orange in autumn. The clusters of fruits, like miniature red plums, ripen in early fall and furnish food for winter birds. The brown bark, divided into squarish blocks, looks like alligator hide. The Indians made a red dye from the smaller roots. The whole year around, the flowering dogwood offers a wealth of color.

This little tree seldom reaches a trunk diameter of six inches but the wood is 90 hard, close-grained, strong and heavy that it has a number of special uses. Because it takes a high polish and will not fray the thread, it is widely used in cotton mills for shuttles, bobbing and spools. Also for the heads of golf clubs, jewelers' blocks and the wooden cogwheels in grandfather clocks.

In the Chicago region there are other species of dogwoods, almost all shrubby, that usually go unrecognized because at first glance they look nothing like the better known flowering dogwood. Like it, however, the veins of the leaf curve and follow the edge toward the tip. The commonest of these is the Gray Dogwood which stands erect, is very leafy, and often forms thickets higher than a man's head. It bears flat clusters of small white flowers in June which are followed by berry-like fruits that turn white and juicy in the fall. The Red-Osier Dogwood thrives on moist soils and shores throughout Cook County. Its stems gleam like red-hot pokers but a cultivated variety, the Yellow Dogwood, has stalks the color of butter. The dried bark of the rather rare Silky Dogwood or Kinnikinnik was smoked by the Indians.

Mangy dogs were washed with a brew of its bark, hence Dogwood.
