Species of medium-sized deciduous Eurasian tree. All parts except the fruit are slightly toxic. The fruit is food for birds and mammals; some also crack open the stones to eat the kernel inside. The leaves provide food for some animals, including the case-bearer moth. The tree exudes a gum from wounds in the bark, by which it seals the wounds to exclude insects and fungal infections.

Species of small cherry tree native to much of Europe and southwest Asia, closely related to the wild cherry (P. avium) but having a fruit that is more acidic. Cultivated sour cherries were apparently selected from wild specimens from around the Caspian and Black Seas; they were popular in Persia and known to the Greeks by the 4th century BCE. The Romans introduced them into Britain by the 1st century CE. In Britain, their cultivation was popular in the time of Henry VIII; by 1640 over 20 named cultivars were recorded.

Species of small deciduous tree native to the Middle East and South Asia, widely cultivated in Europe, east Africa and California. The fruit and oil from the sweet almond variety are used for food while the oil from the bitter almond variety is used for flavoring. Botanically, the fruit of the almond is not a true nut, but a drupe, consisting of an outer hull and a hard shell with the edible seed inside. Although the tree is grown commercially for its fruit and oils, the wood is also used. The water soluble gum that exudes from wounds on the tree has been mentioned as a watercolor binder. Almond trees are closely related to cherry trees.

Species of small tree or large shrub native to middle and southern Europe, western and central Asia, and northwestern Africa. It produces a small thin-fleshed cherry-like drupe, the kernel of which is used in perfumery and as a flavoring that tastes like bitter almond. It is also used in dye-making. The hard wood is used for small objects. The fruits are strung as beads in Africa and Asia. The tree is also used as dwarf stock for grafting branches of cultivated edible cherries.

Small to medium-sized deciduous tree that originated in China and cultivated in warmer climates throughout the world. The scientific name reflects that fact that Europeans formerly thought that the plant was native to Persia.

Genus containing 6 species of coniferous evergreen timber trees native to western North America and eastern Asia. Trees are characterized by having long, flat, spirally arranged needles that grow directly from the branch. Each yellow- or blue-green needle has a short stalk at the base and a grooved upper surface. Winter buds are brown, shiny, and pointed. Uniquely among conifers, the Douglas fir has cones with 3-lobed bracts sticking out between the scales. The cones hang down rather than sticking up as in true firs. Cones mature in one season and retain their scales when they fall.

Species of North American fir tree having several forms, one with reflexed bracts, that are sometimes considered to be separate species. Trees may reach heights in excess of 90 m (295 feet) and have diameters of more than 4 m (13 feet), but most contemporary stands are composed of trees that are much smaller, due to the fact that many old specimens have been logged. It is noted as one of the best timber trees in North America, as well as a popular ornamental and Christmas tree, and is used for reforestation along the Pacific Coast.
