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.

Oriental Bittersweet

Celastrus orbiculatus

Oriental Bittersweet is a deciduous, twining vine known for its aggressive growth habit. It is characterized by its alternate, glossy, round to oval leaves and its showy orange-yellow fruits that split open in the fall to reveal bright red arils. This plant is primarily an outdoor species and is considered an invasive species in many parts of North America due to its ability to outcompete native vegetation. People may unintentionally grow it for its attractive fall and winter berries, often used in wreaths and decorations, unaware of its invasive potential.

❓ 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.

Oriental Bittersweet

What are the light requirements for Oriental Bittersweet?

Oriental Bittersweet prefers full sun, requiring at least six hours of direct sunlight per day for optimal growth and berry production. However, it can tolerate partial shade, especially in hotter climates, where some afternoon shade can prevent leaf scorch. When planting indoors, choose a location near a south-facing or west-facing window to maximize light exposure. If natural light is insufficient, supplement with grow lights to ensure healthy growth and abundant berry production. Insufficient light can result in leggy growth and reduced berry formation.

How do I care for Oriental Bittersweet?

Oriental Bittersweet thrives in full sun to partial shade. Water regularly, especially during dry periods, ensuring the soil remains consistently moist but not waterlogged. Provide a sturdy support structure, such as a trellis or fence, for the vines to climb. Prune annually in late winter or early spring to control its size and shape and to remove any dead or damaged growth. Fertilize in spring with a balanced fertilizer. Monitor for pests and diseases, and treat accordingly. Be mindful of its invasive potential and take measures to prevent its spread, such as removing berries before they ripen.

How do I propagate Oriental Bittersweet?

Oriental Bittersweet can be propagated through stem cuttings or layering. For stem cuttings, take 4-6 inch cuttings from new growth in late spring or early summer. Remove the lower leaves and dip the cut end in rooting hormone. Plant the cuttings in a well-draining potting mix and keep them moist. For layering, bend a low-lying stem to the ground and bury a portion of it, leaving the tip exposed. Secure the buried stem with a rock or landscape staple. Once roots have formed, sever the layered stem from the parent plant and transplant it.
