Flowering Kale vs Puka Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Flowering Kale
Brassica oleracea var. acephala
Flowering kale is a cool-season biennial grown as an annual for its vibrant, colorful foliage. It is not grown for edible leaves like its close relative, edible kale. The plant forms a rosette of ruffled or frilly leaves in shades of white, pink, purple, or red, surrounded by outer green leaves. It is primarily an outdoor plant, thriving in cooler temperatures and full sun. People grow it for its ornamental value, adding color and texture to gardens and containers during the fall and winter months.
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
Flowering Kale Care Tips
Flowering kale is primarily an outdoor plant and requires full sun and cool temperatures to thrive. It is challenging to maintain indoors due to its high light requirements and sensitivity to warm, dry air. Indoor plants often become leggy and lose their color.
- Plant in well-draining soil to prevent root rot.
- Provide at least 6 hours of direct sunlight daily for best color.
- Water regularly, but avoid overwatering.
- Fertilize every 2-4 weeks with a balanced liquid fertilizer.
- Protect from extreme cold or frost if necessary.
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
Flowering Kale
What are the light requirements for Flowering Kale?
Flowering Kale needs at least six hours of direct sunlight per day to develop its best color. Insufficient light can lead to leggy growth and dull coloration. When planting, choose a location that receives full sun exposure. If growing in containers, rotate the plants regularly to ensure even light exposure on all sides.
How do I care for Flowering Kale?
Flowering Kale thrives in cool temperatures (40-70°F) and requires at least 6 hours of sunlight daily. Plant in well-draining soil, enriched with compost or other organic matter. Water regularly, keeping the soil consistently moist but not waterlogged. Fertilize every 2-3 weeks with a balanced fertilizer during the growing season to promote vibrant color.
How do I propagate Flowering Kale?
Flowering Kale is primarily grown from seed, but propagation through stem cuttings is possible, though less common. Take stem cuttings from healthy, non-flowering shoots in late summer or early fall. Dip the cut end in rooting hormone and plant in a well-draining potting mix. Keep the cuttings moist and in a warm, humid environment until roots develop.
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.
