Monkey Puzzle Tree vs Oxalis Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
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.
Oxalis
Oxalis triangularis
Oxalis triangularis is a rhizomatous perennial plant known for its distinctive triangular, purple leaves that resemble shamrocks. These leaves exhibit nyctinastic movement, folding up at night and opening during the day in response to light. It's commonly grown as a houseplant for its unique foliage and relatively easy care. While it can be grown outdoors in suitable climates, it's more often seen as an indoor plant due to its sensitivity to frost. People grow it for its striking appearance and the interesting movement of its leaves.

❓ Frequently Asked Questions — Comparing These Plants
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.
Oxalis
What are the light requirements for Oxalis?
Oxalis plants need bright, indirect light to thrive. Too little light will cause the leaves to become pale and the stems to become leggy. Too much direct sunlight can scorch the leaves, causing brown spots. An ideal location for your Oxalis is near an east- or west-facing window, where it will receive plenty of bright, indirect light without being exposed to harsh direct sunlight.
How do I care for Oxalis?
Oxalis plants thrive in bright, indirect light. Direct sunlight can scorch their delicate leaves, so a location near an east- or west-facing window is ideal. Water your Oxalis when the top inch of soil feels dry to the touch. Avoid overwatering, as this can lead to root rot. Use well-draining potting mix to ensure proper drainage. Fertilize your Oxalis every 2-4 weeks during the growing season (spring and summer) with a balanced liquid fertilizer diluted to half strength.
How do I propagate Oxalis?
Oxalis can be easily propagated through division. Carefully dig up the plant and separate the bulbs or rhizomes. Replant the separated bulbs or rhizomes in individual pots filled with well-draining potting mix. Water thoroughly and place in a bright location with indirect light. Keep the soil consistently moist until new growth appears.
