Living Stone vs Puka Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Living Stone
Lithops spp.
Lithops are fascinating succulent plants that mimic the appearance of pebbles or stones in their native arid environments. They consist of one or more pairs of nearly fused, fleshy leaves that are mostly buried beneath the soil surface, with only the top surface exposed. These surfaces are often patterned with fissures, spots, and lines, providing camouflage. Lithops are grown for their unique appearance and ability to thrive in extremely dry conditions. They are primarily outdoor plants but can be grown indoors with very specific care.
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.

💧 Watering Needs
Living Stone
Water very sparingly, only when the leaves become visibly wrinkled and soft. Overwatering is the most common cause of death. During dormancy (winter), watering should be almost completely stopped. Signs of overwatering include mushy leaves and splitting. Signs of underwatering include excessive wrinkling and shriveling.
Puka
Water thoroughly when the top inch of soil is dry. Ensure good drainage to prevent root rot. Overwatering can lead to yellowing leaves and root rot. Underwatering can cause leaf drop and stunted growth.

💡 Pro Tips For Comparing These Plants
Living Stone Care Tips
Lithops are challenging to grow indoors due to their high light requirements and sensitivity to overwatering. They need very well-draining soil, infrequent watering, and a period of dormancy in winter. Success depends on mimicking their native arid environment.
- Use a terracotta pot to promote drainage.
- Water only when the leaves are visibly wrinkled.
- Provide excellent ventilation to prevent rot.
- Avoid fertilizing during dormancy.
- Repot in fresh soil every 2-3 years.
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
Living Stone
What are the light requirements for Living Stone?
Living Stones thrive in bright, direct sunlight. They need at least 4-6 hours of direct sunlight daily to maintain their compact shape and vibrant colors. An east or south-facing window is ideal. If you don’t have enough natural light, supplement with a grow light. Insufficient light can cause them to stretch and lose their color, a condition known as etiolation. Rotate your plant regularly to ensure even light exposure. Monitor your plant closely and adjust its position as needed to provide optimal light.
How do I care for Living Stone?
Living Stones require very specific care to thrive. Plant them in a well-draining succulent mix with added grit or perlite. Provide them with bright, direct sunlight for at least 4-6 hours daily. Water sparingly, only when the soil is completely dry, typically only a few times a year. Avoid watering during their dormancy period (usually late fall to early spring) when they are splitting. Overwatering is the most common cause of death. Maintain a temperature between 65-80°F (18-27°C). Repot only when necessary, and choose a pot with drainage holes. Fertilize very lightly, if at all, during the growing season (spring and summer).
How do I propagate Living Stone?
Living Stones are typically propagated by seeds or offsets. Offsets are small plants that grow alongside the parent plant. To propagate from offsets, gently separate them from the parent plant when they are large enough to handle. Plant the offsets in well-draining succulent mix. Water sparingly until they establish roots. Seed propagation is more challenging but can be done by sowing seeds on the surface of moist succulent mix. Cover with a clear lid or plastic wrap to maintain humidity. Keep in a warm, bright location until germination occurs. Gradually acclimate the seedlings to drier conditions. Leaf cuttings and stem cuttings are not viable methods for Lithops.
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.
