Gunnera vs Marmalade Bush Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Gunnera
Gunnera manicata
Gunnera manicata, commonly known as Giant Rhubarb, is a massive, rhizomatous perennial plant prized for its enormous, textured leaves. Native to South America, it is primarily an outdoor plant, grown for its dramatic architectural presence in gardens and near water features. The leaves can reach impressive sizes, up to 2.5 meters across, creating a bold statement. While admired for its striking appearance, it is not suitable for indoor cultivation due to its size and specific environmental needs. It produces cone-shaped inflorescences of small reddish-green flowers in the summer.
Marmalade Bush
Streptosolen jamesonii
Streptosolen jamesonii, commonly known as Marmalade Bush, is a sprawling evergreen shrub native to South America. It is prized for its vibrant display of flowers that transition in color from yellow to orange to red, resembling marmalade. Typically grown outdoors in warm climates, it can reach heights of up to 10 feet. The plant features small, ovate, slightly hairy leaves. While it can be grown in containers, it requires significant sunlight and humidity to thrive indoors, making it a challenging indoor plant. People grow it for its showy flowers and tropical appearance.

❓ Frequently Asked Questions — Comparing These Plants
Gunnera
What are the light requirements for Gunnera?
Gunnera thrives in bright, indirect light. Direct sunlight can scorch its large leaves, leading to unsightly brown spots and stunted growth. An east-facing window is often ideal, providing gentle morning sun followed by ample shade throughout the day. If grown indoors, supplement with grow lights if natural light is insufficient. Avoid placing Gunnera in a dimly lit area, as this can result in leggy growth and smaller, less vibrant leaves. Rotate the plant regularly to ensure even light exposure on all sides. If growing outdoors, choose a location that receives partial shade, particularly during the hottest part of the day.
How do I care for Gunnera?
Gunnera demands consistent moisture and high humidity to thrive. Position in bright, indirect light, avoiding direct sunlight which can scorch the leaves. Water generously, ensuring the soil remains consistently damp but not waterlogged. A well-draining soil mix rich in organic matter is crucial. Fertilize regularly during the growing season (spring and summer) with a balanced liquid fertilizer diluted to half strength. Prune away dead or damaged leaves to encourage new growth and maintain plant health. Provide adequate space for the plant to grow, as it can reach significant sizes. Consider using a humidifier or pebble tray to increase humidity levels, especially indoors. Protect from frost and extreme temperatures. Regularly inspect for pests and diseases, addressing any issues promptly.
How do I propagate Gunnera?
Gunnera can be propagated through stem cuttings, division, or air layering. For stem cuttings, take a cutting from a healthy stem and root it in water or moist potting mix. For division, carefully separate the rhizome into smaller sections, ensuring each section has roots and leaves. Plant each section in its own pot. Air layering involves wrapping a section of stem with moist sphagnum moss and covering it with plastic wrap until roots develop. Once roots have formed, cut the stem below the roots and plant in its own pot. Maintain high humidity and consistent moisture during the propagation process. Spring and early summer are the best times for propagation. Ensure proper sanitation to prevent fungal infections.
Marmalade Bush
What are the light requirements for Marmalade Bush?
Marmalade Bush requires bright, indirect sunlight to thrive and produce abundant blooms. An east or west-facing window is often ideal. Avoid direct sunlight during the hottest part of the day, as this can scorch the leaves. If growing indoors, consider supplementing with a grow light if natural light is insufficient, especially during winter months. Insufficient light can lead to leggy growth and reduced flowering. Rotate the plant regularly to ensure even light exposure on all sides. Observe the leaves for signs of sun stress, such as bleaching or browning, and adjust the plant’s location accordingly.
How do I care for Marmalade Bush?
Marmalade Bush thrives in bright, indirect sunlight. Direct sunlight can scorch the leaves, so a location with filtered light is ideal. Water thoroughly when the top inch of soil feels dry to the touch, ensuring good drainage to prevent root rot. Fertilize regularly during the growing season (spring and summer) with a balanced, water-soluble fertilizer diluted to half strength, or a fertilizer specifically formulated for blooming plants. Prune lightly after flowering to encourage bushier growth and more blooms. Maintain a temperature between 60-75°F (15-24°C) and provide moderate humidity. Repot in spring every 1-2 years, using a well-draining potting mix. Protect from frost, as it is not cold-hardy. Regular inspection for pests such as aphids and spider mites is crucial.
How do I propagate Marmalade Bush?
Marmalade Bush can be propagated using stem cuttings. Take 4-6 inch cuttings from healthy stems. Remove the lower leaves and dip the cut end in rooting hormone. Plant the cuttings in a well-draining potting mix and keep moist. Cover with a plastic bag to create humidity. Rooting typically occurs in 4-6 weeks. Alternatively, division can be done by carefully separating the root ball of a mature plant. Keiki propagation is not applicable for Marmalade Bush. Ensure the cuttings receive bright, indirect light during the rooting process. Maintain consistent moisture but avoid overwatering.
