Charles H. Spurgeon on Psalms 137:2

"Willows." The Weeping Willow of Babylon will grow to be a large tree; its branches being long, slender, and pendulous, makes it proper to be planted upon the banks of rivers, ponds, and over springs; the leaves, also, are long and narrow; and when any mist or dew falls, a drop of water is seen hanging at their extremities, which, together with with their hanging branches, cause a most lugubrious appearance. Lovers' garlands are said to have been made of a species of this willow, the brancehs of which are very slender and pliable; and the the plant itself has always been sought after for ornamental plantations, either to mix with others of the like growth in the largest quaters, of to be planted out singly over springs, or in large opens, for the peculiar variety occasioned by its mournful look. —John Evelyn (1620-1706) in "Silva; or, A Discourse of Trees."
