distribution_en:

description_en: Genus of40-70 species of evergreen, conifer-like trees and shrubs from Australia and the Pacific islands, where they thrive in a range of habitats from semi-desert to swamp forest. They are cultivated for their foliage, which is modified into minute scales or teeth arranged in a collar-like ring at each node. The tiny, petalless flowers are borne in single-sexed, cone-like spikes. Some species have nitrogen-fixing bacterial nodules on their roots. In frost-prone areas, grow young plants in a cool or temperate conservatory or green-house, or as houseplants. In frost-free climates, use Australian pines as specimen trees, windbreaks, or screens. They are tolerant of strong winds, coastal conditions, and wet or dry soils.

hardiness_en: Mostly frost tender, but C. equisetifolia and C. torulosa will tolerate short spells near to 0°C (32°F).
