The Norfolk Island Pine (Araucaria heterophylla) is another option for having a live Christmas tree during the holiday season. This tree is quite different from a typical pine in the Iowa landscape. It is a tropical plant, and must remain indoors during the winter months.
It is not uncommon to also bring in some insects or spiders that were on the tree while it was growing outdoors. Fortunately, these “accidental invader” insect and spider pests are harmless.
