Cupressus in the context of Native plant

Cupressus sempervirens, the Mediterranean cypress (also known as Italian cypress, Tuscan cypress, or Persian cypress), is a species of cypress native to the eastern Mediterranean region and Iran. It is well-adapted to the environmental conditions that it lives in due to its ability to survive in both acidic and alkaline soils and withstand drought. Cupressus sempervirens is important in Mediterranean and Middle Eastern culture, most notably in Iran, where it is both a sacred tree and a metaphor for "the graceful figure of the beloved".

The order Pinales in the division Pinophyta, class Pinopsida, comprises all the extant conifers. The distinguishing characteristic is the reproductive structure known as a cone produced by all Pinales. All of the extant conifers, such as Araucaria, cedar, celery-pine, cypress, fir, juniper, kauri, larch, pine, redwood, spruce, and yew, are included here. Some fossil conifers, however, belong to other distinct orders within the division Pinophyta.

Multiple molecular studies indicate this order being paraphyletic with respect to Gnetales, with studies recovering Gnetales as either a sister group to Pinaceae or being more derived than Pinaceae but sister to the rest of the group.

Cupressus torulosa, commonly known as the Himalayan cypress or Bhutan cypress, is a species of cypress tree native to the mountainous northern regions of the Indian subcontinent, in the western Himalayas.
