The world's tallest, thickest, largest, and oldest living trees are all conifers. The tallest is a coast redwood (Sequoia sempervirens), with a height of 115.55 metres (although one mountain ash, Eucalyptus regnans, allegedly grew to a height of 140 metres, [16] the tallest living angiosperms are significantly smaller at around 100 metres.
A conifer cone, or in formal botanical usage a strobilus, pl.: strobili, is a seed-bearing organ on gymnosperm plants, especially in conifers and cycads. They are usually woody and variously conic, cylindrical, ovoid, to globular, and have scales and bracts arranged around a central axis, but can be fleshy and berry -like.
The Cupressaceae trees contain a wide range of extractives, especially terpenes and terpenoids, [39] both of which have strong and often pleasant odors. The heartwood, bark and leaves are the tree parts richest in terpenes. [40] Some of these compounds are widely distributed in other trees as well, and some are typical for Cupressaceae family.

Giant sequoia. Silvics of North America (1991), [1] a forest inventory compiled and published by the United States Forest Service, includes many conifers. [a] It superseded Silvics of Forest Trees of the United States (1965), which was the first extensive American tree inventory. [3]
Junipers are coniferous trees and shrubs in the genus Juniperus (/ dʒ uː ˈ n ɪ p ər ə s / joo-NIP-ər-əs) [1] of the cypress family Cupressaceae.Depending on the taxonomy, between 50 and 67 species of junipers are widely distributed throughout the Northern Hemisphere as far south as tropical Africa, including the Arctic, parts of Asia, and Central America.
They are pale blue-green and deciduous, [3] turning golden yellow in autumn. The seed cones, 2.5 to 4 centimeters (1 to 1 + 1 ⁄ 2 in) long, are red-purple when young but become dark brown with age. They have thin scales and narrow bracts that extend over the scales. The pollen and seed cones become active in early summer. [3]
