An illustration of a portion of a date palm leaf. The Date Palm (Phoenix dactylifera) is a palm in the genus Phoenix, extensively cultivated for its edible fruit. Due to its long history of cultivation for fruit, its exact native distribution is unknown, but probably originated somewhere in the desert oases of northern Africa, and perhaps also southwest Asia. It is a medium-sized tree, 15–25 m tall, often clumped with several trunks from a single root system, but often growing singly as well. The leaves are pinnate, 3–5 m long, with spines on the petiole and about 150 leaflets; the leaflets are 30 cm long and 2 cm broad. The full span of the crown ranges from 6–10 m.

Leaves - simple, alternate (often crowded at the ends of the branches); edge entire. Outline - broadly oval or egg-shape or reverse egg-shape. Apex - pointed. Base - slightly pointed. Leaf/Stem - one inch long or more. Leaf - about three to four inches long, sometimes yellowish-green; smooth above; whitish beneath, and slightly rough between the prominent curved ribs, seldom entirely flat, usually in clusters at the ends of the branches. Bark - of the branches, smooth, yellowish-green, with whitish streaks. Flowers - yellowish in loose flat clusters. June. Fruit - very dark blue when ripe, on reddish stems. August. Found - in low rich woods and along streams, from New Brunswick through the Northern States, and southward along the Alleghany Mountains to Northern Georgia and Alabama. General Information - A small tree or shrub, ten to twenty feet high, with wide-spreading branches and flattish top. A "Shaker Medicine" is made from its bitter bark. Cornus, from a Greek word meaning horn, because of the hardness of the wood.

Leaves - simple; opposite; edge entire. Outline - egg-shape, or often broad oval, or reverse egg-shape. Apex - pointed, often taper-pointed. Base - pointed and usually slightly unequal. Leaf/Stem - short (about one half inch). Leaf - three to five inches long; smooth above; pale and nearly smooth beneath; with the whitish ribs very distinct and curved. Bark - of trunk, blackish and rough, with short, broken ridges. The bark, especially of the roots, is very bitter and is used as a tonic. Flowers - The real flowers are greenish-yellow, in a small rounded bunch; but this bunch is surrounded by four large, petal-like leaves, white and often tinged with pink, more than an inch in length, reverse egg-shaped, and ending in a hard, abruptly turned point. The appearance is of a single large flower. The tree blossoms in May before the leaves are fully set. Fruit - The "Flower" is succeeded by a bunch of oval berries that turn bright red as they ripen, making the tree in the autumn, with its richly changing foliage, nearly as attractive as in the spring. Found - in rich woods, from New England to Minnesota, and southward to Florida and Texas. It is very common, especially at the South. General Information - A finely shaped, rather flat-branching tree, usually twelve to thirty feet high, but dwindling, northward, to the dimensions of a shrub; one of the most ornamental of all our native flowering trees. Its character throughout the extent of its range would seem to warrant the recognition of its blossom as the "national flower." Cornus, from a Greek word meaning horn, because of the hardness of the wood.
