Eucalyptus vs Monkey Puzzle Tree Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Eucalyptus
Eucalyptus globulus
Eucalyptus globulus is a fast-growing evergreen tree, typically reaching heights of 30-55 meters (100-180 feet) in its native habitat. It features smooth, bluish-white bark that peels away in strips. Juvenile leaves are opposite, ovate, and bluish-grey, while mature leaves are alternate, lanceolate, and dark green. It's primarily grown for its aromatic foliage and timber production. Due to its size and specific needs, it is rarely grown indoors.
Monkey Puzzle Tree
Araucaria araucana
The Monkey Puzzle Tree is an ancient evergreen conifer known for its distinctive, scale-like leaves and unusual branching pattern. It is a slow-growing, dioecious tree, meaning male and female cones are borne on separate plants. Native to the Andes, it can live for over 1,000 years. While highly prized as an ornamental tree for its unique appearance, it is primarily an outdoor plant and extremely challenging to grow indoors due to its size and specific environmental needs. People grow it for its striking architectural form and historical significance.

❓ Frequently Asked Questions — Comparing These Plants
Eucalyptus
What are the light requirements for Eucalyptus?
Eucalyptus thrives in bright, direct sunlight, requiring at least 6-8 hours of direct sun exposure daily. Insufficient light can lead to leggy growth and leaf drop. The best placement for your Eucalyptus is near a south-facing window or a location with unobstructed sunlight. If natural light is limited, supplement with a grow light to ensure optimal growth.
How do I care for Eucalyptus?
To thrive indoors, Eucalyptus requires bright, direct sunlight for at least 6-8 hours daily. Use a well-draining potting mix, such as a blend of perlite, sand, and potting soil, to prevent waterlogging. Water thoroughly when the top inch of soil is dry, ensuring excess water drains away. Maintain moderate humidity levels, ideally between 40-60%.
How do I propagate Eucalyptus?
Eucalyptus can be propagated through stem cuttings or air layering. For stem cuttings, take a 4-6 inch cutting from a healthy stem, removing the lower leaves. Dip the cut end in rooting hormone and plant in a well-draining potting mix. Keep the soil moist and provide bright, indirect light. Rooting typically occurs in 4-6 weeks.
Monkey Puzzle Tree
What are the light requirements for Monkey Puzzle Tree?
Monkey Puzzle Trees thrive in bright, indirect light indoors. Avoid placing them in direct sunlight, especially during the hottest part of the day, as this can scorch their leaves. An east-facing window is often ideal, providing gentle morning light. A south- or west-facing window can work if you diffuse the light with a sheer curtain. Insufficient light can lead to weak growth and sparse foliage. Rotate the plant regularly to ensure even light exposure on all sides. Supplement with artificial grow lights if natural light is limited, especially during winter months.
How do I care for Monkey Puzzle Tree?
Monkey Puzzle Trees require bright, indirect light indoors. Direct sunlight can scorch their foliage. Water thoroughly when the top inch of soil feels dry, but avoid overwatering, as this can lead to root rot. Use well-draining potting mix. Maintain moderate humidity levels. Fertilize sparingly, only during the growing season (spring and summer) with a balanced, diluted liquid fertilizer. Repot only when necessary, as they prefer to be slightly root-bound. Prune only to remove dead or damaged branches. Provide stable temperature and humidity. Regular cleaning of the leaves will help with photosynthesis. Pot size should be adequate for root growth but not excessively large.
How do I propagate Monkey Puzzle Tree?
Propagating Monkey Puzzle Trees indoors is challenging but possible. Stem cuttings are difficult to root. Take stem cuttings in spring or early summer, ideally from the current year’s growth. Apply rooting hormone to the cut end and plant in a well-draining potting mix. Maintain high humidity by covering the cutting with a plastic bag or humidity dome. Air layering is another potential method. Make a shallow cut on a branch, wrap it with moist sphagnum moss, and cover with plastic wrap. Once roots develop, sever the branch below the moss and pot it up. Be patient, as rooting can take several months.
