Cupressus

Lore & Background

The name Cupressus derives from the mythological figure Cyparissus, who was transformed into a tree by Apollo after accidentally killing a stag. In Hellenic culture, the cypress was considered sacred to the gods and became an emblem of grief, a tradition that continued into Roman times and persists today, partly because its roots grow straight down and do not disturb burials.

Cypress trees are evergreen, growing 5–40 m tall. Their leaves are scale-like and arranged in opposite pairs, while young plants have needle-like leaves. The cones are globose or ovoid, with 4 to 14 scales, and take 18–24 months to mature. Many species are adapted to forest fires, holding seeds in closed cones until fire kills the parent tree, then releasing them onto bare ground.

The genus is considered polyphyletic, with Old World species more closely related to Juniperus, and New World species (sometimes placed in Hesperocyparis or Callitropsis) more closely related to Xanthocyparis. The number of recognised species varies from 16 to 25 or more, due to small, isolated populations and taxonomic uncertainty.

Reader's Guide

Cupressus holds significance both ecologically and culturally. Ecologically, many species are fire-adapted, releasing seeds only after wildfires, which allows them to colonise disturbed landscapes. Their timber is durable, and the fast-growing hybrid Leyland cypress (Cupressus × leylandii) is widely used in gardens. Culturally, the cypress has been a symbol of mourning since ancient Greek and Roman times, linked to the myth of Cyparissus.

Its roots grow straight down, making it suitable for planting near graves without damaging burials. The genus is also notable for its allergenic potential: all Cupressus species, including New World ones, have an OPALS allergy scale rating of 10, releasing large amounts of pollen for about seven months each year in warm Mediterranean climates. Taxonomic debate continues, with genetic evidence suggesting that New World species may belong to separate genera, reflecting ongoing refinement of conifer classification.
