Araucaria — 6 species

Araucaria is a genus of striking conifers ranging from the graceful Norfolk Island Pine — a popular indoor tree — to the dramatic, spiky Monkey Puzzle Tree and the massive Bunya Pine. Indoors, they prefer bright, indirect light and consistently moist but well-drained soil; avoid letting them dry out completely. Toxicity varies across species: the Norfolk Island Pine (A. heterophylla) is listed as toxic to cats by the ASPCA, while the Monkey Puzzle Tree is considered non-toxic. Always verify the specific species before bringing one home with pets.
