Blazing Star vs Gunnera Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Blazing Star
Liatris spicata
Liatris spicata, commonly known as Blazing Star, is a perennial herbaceous plant prized for its striking vertical flower spikes. Native to moist meadows and prairies, it typically grows 2-5 feet tall. The plant features grass-like foliage and dense spikes of purple, pink, or white flowers that bloom from the top down, unlike most plants. It is primarily grown outdoors in gardens and naturalized areas for its pollinator-attracting qualities and unique floral display. While occasionally attempted indoors, it struggles due to high light requirements and dormancy needs.
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.

❓ Frequently Asked Questions — Comparing These Plants
Blazing Star
What are the light requirements for Blazing Star?
Blazing Star requires full sun for optimal growth and flowering, meaning at least six hours of direct sunlight each day. Insufficient sunlight can result in leggy growth, reduced flowering, and weaker stems. When planting Blazing Star in a garden, choose a location that receives ample sunlight throughout the day. If growing in containers, place them in a sunny spot, such as a south-facing patio or balcony. Rotate the containers periodically to ensure even light exposure on all sides of the plant. In regions with intense summer heat, some afternoon shade may be beneficial to prevent scorching of the foliage. Monitor the plant’s growth and adjust its location as needed to ensure it receives adequate sunlight.
How do I care for Blazing Star?
Blazing Star thrives in well-drained soil and full sun, requiring at least six hours of direct sunlight daily. Water deeply but infrequently, allowing the soil to dry out slightly between waterings. Avoid overwatering, as this can lead to root rot. Fertilize sparingly, using a balanced fertilizer in the spring to encourage healthy growth and abundant blooms. Deadhead spent flower spikes to promote continued blooming. In colder climates, provide winter protection by mulching around the base of the plant. Blazing Star is relatively low-maintenance and pest-resistant, making it an easy-to-grow addition to any garden. Ensure good air circulation to prevent fungal diseases. Divide established clumps every few years to rejuvenate the plant and prevent overcrowding. Regularly check for any signs of pests or diseases and address them promptly.
How do I propagate Blazing Star?
Blazing Star can be propagated by division, stem cuttings, or seeds.
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.
