Plants in genus araucaria
Araucaria heterophylla
Araucaria heterophylla, commonly known as the Norfolk Island pine, is a species of conifer endemic to Norfolk Island. It is often grown as an ornamental plant and is recognized for its symmetrical, tiered branches and soft, needle-like leaves.
Araucaria araucana
The Araucaria araucana, commonly known as the monkey puzzle tree, is an evergreen conifer native to Chile and Argentina. It is recognized for its unique, spiny branches and thick, scale-like leaves, earning it the nickname 'living fossil.' This tree is the national tree of Chile and is considered endangered due to threats like forest fires and overharvesting. It thrives in well-drained, slightly acidic volcanic soil and can withstand temperatures as low as -4°F. The tree is dioecious, meaning male and female cones grow on separate trees, and it takes 30 to 40 years to produce seeds. Its seeds are edible and have been traditionally harvested by indigenous peoples. The monkey puzzle tree is popular in gardens for its unusual appearance and can grow up to 10 feet tall in 10 years under suitable conditions.
Araucaria bidwillii
Araucaria bidwillii, also known as the Bunya Pine, is a large evergreen conifer native to Australia. It can grow up to 160 feet tall with a distinctive egg-shaped silhouette and edible seeds. This tree has cultural significance to Australian Aboriginal peoples and can live for about 500 years.
