Araucaria heterophylla

Common Name(s):

Description

Araucaria heterophylla is a tropical needled evergreen tree that is commonly grown as a houseplant in temperate climates. Evergreen small tree to 9' 10" (indoors). For indoors, use fertile, porous, sandy, peaty, slightly acidic, well-drained soils in fairly cool conditions (55-65 degrees F). Full sun is normally best for developing compact symmetrical growth, but some light afternoon shade may be needed to avoid possible foliage bleach (yellow tints). As a houseplant, it will generally adapt to the warm, dry atmosphere found in most offices and homes. Consider weekly or biweekly applications of dilute liquid fertilizer from spring through fall. Avoid soils that are too soggy or too dry.

Slow growing plant; tolerates low to high light; prefers dry soil, medium relative humidity; prefers cool temperatures; has pest problems. Mist in heated rooms in winter; water regularly spring to autumn, sparingly in winter.

Specimen tree. Branches have tiered growth pattern. Branches form herringbone (flat-plane) pattern and feel like a bottle brush. Grows to 197' in native habitat (S. America). Plant will often stay beautiful 2-3 years under very low light. Major problem is leaf drop & loss of lower branches. 

 

Quick ID Hints:

  • Evergreen small tree with saber-like leaves
