Next to the color of the ocean, in its power to suggest remoteness and unfamiliarity, is the character of the vegetation. The flora of Key West is wholly tropical, and in my first ramble through the city I did not discover a single plant, shrub, tree, or flower that I had ever seen in the North except the oleander. Even that had wholly changed its habits and appearance, and resembled the pot-grown plant of Northern households only as the gigantic sequoia of California resembles the stunted Lilliputian pine of the Siberian tundra. The Key West oleander is not a plant, nor a shrub; it is a tree. In the yard of a private house on Carolina Street I saw an oleander nearly thirty feet in height, whose branches shaded an area twenty feet or more in diameter, and whose mammoth clusters of rosy flowers might have been counted by the hundred. Such an oleander as this, even though its leaves and blossoms may be familiar, seems like a stranger and an exotic, and, instead of modifying the impression of remoteness and alienation made by the other features of the tropical environment, it deepens and intensifies it. Among the vines, plants, shrubs, and trees that I noticed and identified in the streets and private grounds of Key West were jasmine, bergamot, poinsettia, hibiscus, almond, banana, sapodilla, tamarind, Jamaica apple, mango, Spanish lime, cotton-tree, royal poinciana, "Geiger flower" (a local name), alligator-pear, tree-cactus, sand-box, cork-tree, banian-tree, sea-grape, cocoanut-palm, date-palm, Indian laurel, Australian pine, and wild fig. Most of these trees and shrubs do not grow even in southern Florida, and are to be found, within the limits of the United States, only in southern California and on the island of Key West. A mere perusal of this long list of unfamiliar names will enable the reader to understand why the vegetation of the island reinforces the impression of strangeness and remoteness already made by the color of the sea.
