Cupressus macrocarpa; Cupressaceae
is a medium-sized coniferous evergreen tree, which often becomes irregular and flat-topped as a result of the strong winds that are typical of its native area. It grows to heights of up to 40 meters in perfect growing conditions, and its trunk diameter can reach 2.5 meters. The foliage grows in dense sprays which are bright green in color and release a deep lemony aroma when crushed. The leaves are scale-like, 2–5 mm long, and produced on rounded (not flattened) shoots; seedlings up to a year old have needle-like leaves 4–8 mm long.The seed cones are globose to oblong, 20–40 mm long, with 6–14 scales, green at first, maturing brown about 20–24 months after pollination. The pollen cones are 3–5 mm long, and release their pollen in late winter or early spring.It has been widely reported that individual C. macrocarpa trees may be up to 2,000 years old, but this is disputed by botanists, and the longest-lived report based on physical evidence is of a tree 284 years old. The renowned Californian botanist Willis Linn Jepson wrote that "the advertisement of [C. macrocarpa trees] in seaside literature as 1,000 to 2,000 years old does not ... rest upon any actual data, and probably represents a desire to minister to a popular craving for superlatives".
Along with other New World Cupressus species, it has recently been transferred to the genus Hesperocyparis, on genetic evidence that the New World Cupressus are not very closely related to the Old World Cupressus species.
'Goldcrest' is a columnar, evergreen conifer with bright golden-yellow foliage in ascending sprays, colour persisting into winter.
