Bells of Ireland vs Monkey Puzzle Tree Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Bells of Ireland
Moluccella laevis
Bells of Ireland is an annual flowering plant known for its tall spikes of vibrant green, bell-shaped calyces (modified leaves) that surround tiny, inconspicuous white flowers. It typically grows to a height of 2-3 feet. While it can be grown indoors, it's primarily an outdoor plant, often cultivated in gardens for its unique architectural form and long-lasting cut flowers. People grow it for its ornamental value, particularly in floral arrangements, where its bright green color adds a striking contrast.
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
Bells of Ireland
What are the light requirements for Bells of Ireland?
Bells of Ireland crave sunlight. They need at least 6-8 hours of direct sunlight each day to produce vibrant green calyces and strong stems. Insufficient light can lead to leggy growth, pale coloring, and reduced blooming. When grown indoors, place them near a south-facing window where they can receive ample sunlight. If natural light is limited, supplement with grow lights. Rotate the plants regularly to ensure even light exposure on all sides. When starting seeds indoors, use grow lights to ensure healthy seedling development.
How do I care for Bells of Ireland?
Bells of Ireland require full sun, at least 6-8 hours daily, to thrive. Plant them in well-draining soil with a slightly acidic to neutral pH (6.0-7.0). Water regularly, keeping the soil consistently moist but not waterlogged, especially during hot weather. Fertilize every 2-3 weeks with a balanced liquid fertilizer during the growing season (spring and summer).
How do I propagate Bells of Ireland?
Bells of Ireland are typically propagated by seed.
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.
