Araucaria comprises evergreen trees native to the Southern Hemisphere. These trees feature whorled branching and leaves that can be needle-like, triangular, or scale-like in appearance. They produce small male cones and larger female cones, typically found on different specimens.

Araucaria

Araucaria angustifolia is a sizable evergreen tree that exhibits a slender, pyramidal form in its youth, gradually transitioning to a more rounded shape as it matures. Its leaves are thick, triangular, and measure between 3 to 6 cm in length, featuring sharp edges and tips. These leaves are arranged in a spiral pattern along the branchlets, with tufted clusters often found at the tips. This species typically has male and female cones on separate trees; the male cones are elongated, reaching lengths of up to 18 cm, while the female cones are spherical, ranging from 18 to 25 cm in diameter, and can remain on the tree for as long as three years post-pollination.

Araucaria bernieri

Araucaria bidwillii is a sizable conifer that can reach heights of up to 45 meters, featuring whorled branches. In its youth, the tree exhibits a conical shape that matures into a more rounded form as it ages, leading to the loss of its lower branches. The leaves are flattened and glossy, with spiny tips; they are arranged in a spiral pattern when young and become overlapping as they mature. This species produces large cones that can measure up to 30 centimeters in length, starting green and turning brown upon ripening. The cones contain edible seeds.

Araucaria columnaris

Araucaria cunninghamii is a tall, frost-sensitive conifer that can grow over 50 meters in height. Its bark is rough and reddish-brown, shedding in circular strips. The juvenile foliage consists of awl-shaped leaves that can reach up to 2 centimeters in length and are spirally arranged, while the mature leaves transform into scale-like structures that curve inward. Male cones are cylindrical, measuring 2 to 3 centimeters, whereas the female cones are ovoid, measuring between 8 and 10 centimeters. These cones appear on mature specimens and break apart upon ripening to disperse their nut-like seeds.

Araucaria heterophylla is a coniferous tree characterized by its conical shape and unique whorled branches. The juvenile leaves are flat and arranged in a fan-like pattern, while the mature foliage features a spiral arrangement. Young specimens are frequently cultivated as indoor plants.
