Italian Arum vs Puka Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Italian Arum
Arum italicum
Italian Arum is a herbaceous perennial known for its striking foliage and distinctive spadix and spathe flower structure. It emerges in autumn with arrow-shaped, glossy green leaves often marked with prominent white veins. In late spring, it produces a creamy-white spathe surrounding a yellow spadix, followed by clusters of bright orange-red berries. Primarily an outdoor plant, it thrives in woodland settings. People grow it for its ornamental foliage and colorful berries, which add visual interest to gardens, especially during the dormant winter months. It is not naturally suited for indoor environments.
Puka
Meryta sinclairii
Meryta sinclairii, commonly known as the Puka Tree, is a striking evergreen tree native to New Zealand. It is characterized by its large, leathery, paddle-shaped leaves that can grow up to 50 cm long. The tree typically grows to a height of 4-8 meters in its natural habitat, but is much smaller when container grown. It is primarily grown for its bold foliage and architectural form. While it can be grown indoors, it requires very bright light and high humidity to thrive, making it a challenging houseplant. It is more commonly cultivated as an ornamental tree in subtropical and warm temperate gardens.

💡 Pro Tips For Comparing These Plants
Italian Arum Care Tips
Italian Arum is primarily an outdoor plant and is challenging to grow indoors. It requires specific light, temperature, and humidity conditions that are difficult to replicate indoors. It also spreads aggressively via rhizomes, quickly outgrowing containers. Toxicity to pets is a major concern.
- Plant in well-draining soil to prevent rhizome rot
- Provide shade to protect leaves from scorching
- Monitor for pests and diseases regularly
- Divide rhizomes every few years to control spreading
- Wear gloves when handling to avoid skin irritation from the sap
Puka Care Tips
Puka Trees are challenging to grow indoors due to their high light and humidity requirements. They need very bright light, well-draining soil, and consistent moisture. Regular fertilization and pruning are necessary to maintain their shape. They are prone to pests and diseases if not properly cared for.
- Provide supplemental light if natural light is insufficient.
- Mist regularly to increase humidity or use a humidifier.
- Ensure excellent drainage to prevent root rot.
- Fertilize regularly during the growing season.
- Inspect regularly for pests and diseases.

❓ Frequently Asked Questions — Comparing These Plants
Italian Arum
What are the light requirements for Italian Arum?
Italian Arum prefers partial to full shade, making it an ideal plant for areas with limited sunlight. While it can tolerate some morning sun, prolonged exposure to direct sunlight can scorch the leaves. When grown indoors, place the plant near a north-facing window or in a location that receives filtered light. If leaves start to turn pale or yellow, it may be receiving too much light.
How do I care for Italian Arum?
Italian Arum thrives in partial to full shade, requiring minimal direct sunlight. Plant in well-draining soil rich in organic matter. Water regularly during the growing season, keeping the soil consistently moist but not waterlogged. Reduce watering significantly during the dormant period in summer. Fertilize in early spring with a balanced, slow-release fertilizer to promote healthy growth and flowering.
How do I propagate Italian Arum?
Italian Arum can be propagated by division or by seed. Division is the most common and easiest method. In late summer or early fall, carefully dig up the plant and gently separate the corms. Ensure each division has healthy roots and foliage. Replant the divisions in well-draining soil, spacing them appropriately. Water thoroughly after planting. Seeds can be collected from the ripe berries, but germination can be slow and inconsistent.
Puka
What are the light requirements for Puka?
Puka trees prefer bright, indirect light. Direct sunlight can scorch their leaves, so avoid placing them in direct contact with intense sun. An east-facing window is ideal, providing gentle morning light. A north-facing window can also work, but the plant may grow more slowly. If you only have south- or west-facing windows, place the Puka tree a few feet away from the window or use sheer curtains to filter the light. Insufficient light can lead to leggy growth and a lack of vibrancy in the leaves. Rotate the plant regularly to ensure even light exposure on all sides.
How do I care for Puka?
Puka trees thrive in bright, indirect light, but can tolerate lower light conditions. Water when the top inch of soil is dry, allowing the soil to dry out slightly between waterings. Avoid overwatering, which can lead to root rot. Use a well-draining potting mix. Maintain moderate humidity levels. Fertilize every 2-3 months during the growing season (spring and summer) with a balanced liquid fertilizer diluted to half strength. Prune to maintain shape and remove any dead or yellowing leaves. Repot every 1-2 years, or when the plant becomes root-bound, using a pot that is one size larger. Provide stable temperatures between 65-80°F (18-27°C). Protect from drafts and sudden temperature changes. Watch out for pests such as spider mites and mealybugs, and treat promptly if detected.
How do I propagate Puka?
Puka trees can be propagated through stem cuttings or air layering. For stem cuttings, take a 4-6 inch cutting from a healthy stem. Remove the lower leaves and dip the cut end in rooting hormone. Plant the cutting in a well-draining potting mix. Keep the soil moist and provide bright, indirect light. Rooting should occur in 4-6 weeks. For air layering, make a small cut on a stem and wrap it with moist sphagnum moss. Cover the moss with plastic wrap and secure it with tape. Keep the moss moist. Roots should form within a few weeks. Once roots are visible, cut the stem below the rooted section and plant it in a pot.
