Giant Reed vs Little Bluestem Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Giant Reed
Arundo donax
Giant Reed is a tall, perennial grass characterized by its robust, cane-like stems and feathery plumes. It can reach heights of up to 6 meters (20 feet) or more. The plant spreads aggressively via rhizomes, forming dense thickets. While primarily an outdoor plant valued for erosion control, screening, and ornamental purposes, it is rarely grown indoors due to its size and high light requirements. Its rapid growth and invasive nature make it a challenging plant to manage.
Little Bluestem
Schizachyrium scoparium
Little Bluestem is a perennial bunchgrass native to North America. It's known for its striking blue-green foliage during the growing season, which transitions to a beautiful reddish-bronze in the fall and winter. It typically grows to a height of 2-4 feet. It is primarily an outdoor plant, valued for its ornamental appeal in native plant gardens, meadows, and prairie restorations. People grow it for its drought tolerance, low maintenance, and seasonal color changes. It provides habitat and food for wildlife.

💧 Watering Needs
Giant Reed
Water deeply and regularly during the growing season, especially when newly planted. Established plants are relatively drought-tolerant but benefit from occasional watering during dry periods. Overwatering can lead to root rot, indicated by yellowing leaves and a foul odor from the soil. Underwatering results in wilting and browning of leaf tips.
Little Bluestem
Water deeply when the top inch of soil is dry. Overwatering can lead to root rot, especially in poorly draining soils. Underwatering will cause the foliage to turn brown and crispy. Established plants are very drought-tolerant.

❓ Frequently Asked Questions — Comparing These Plants
Giant Reed
What are the light requirements for Giant Reed?
Giant Reed requires at least 6-8 hours of direct sunlight per day to thrive. Insufficient light can lead to weak growth, leggy stems, and reduced flowering. When planting in a container, choose a location that receives full sun throughout the day. If growing indoors, a south-facing window is ideal. Supplemental lighting, such as grow lights, may be necessary if natural light is limited. Rotate the plant regularly to ensure even light exposure on all sides. Observe the plant’s growth and adjust its position as needed to maximize sunlight absorption.
How do I care for Giant Reed?
Giant Reed thrives in full sun and prefers consistently moist to wet conditions. If grown in a container, use a large pot with drainage holes and place it in a tray filled with water to ensure constant moisture. For in-ground planting, choose a location near a water source or amend the soil with plenty of organic matter to improve water retention. Fertilize monthly during the growing season (spring and summer) with a balanced liquid fertilizer diluted to half strength. Prune dead or damaged stems regularly to maintain its appearance and prevent overcrowding. Monitor for pests and diseases, and address any issues promptly. Provide winter protection in colder climates by mulching around the base of the plant. Maintain good water quality by regularly changing water in containers and ensuring adequate circulation in ponds.
How do I propagate Giant Reed?
Giant Reed is easily propagated through division or cuttings. For division, carefully dig up a mature clump and separate it into smaller sections, ensuring each section has healthy roots and stems. Replant the divisions in separate containers or directly into the ground. For cuttings, take 6-8 inch stem cuttings in spring or summer. Place the cuttings in water, ensuring that the nodes are submerged. Roots should develop within a few weeks. Once roots are established, transplant the cuttings into pots filled with moist soil or directly into the ground near a water source. Keep the soil consistently moist until the plants are well-established.
Little Bluestem
What are the light requirements for Little Bluestem?
Little Bluestem requires at least six hours of direct sunlight per day to thrive. A sunny location is essential for optimal growth, vibrant color, and strong stems. Insufficient light can result in weak, floppy growth and reduced flowering. Choose a planting site that receives full sun throughout the day.
How do I care for Little Bluestem?
Little Bluestem is relatively easy to care for, thriving in full sun and well-drained soil. Water newly planted grasses regularly until established, then reduce watering frequency as they become more drought-tolerant. Fertilize sparingly in spring with a balanced fertilizer or compost. Avoid over-fertilizing, as this can cause the grass to become leggy and flop over.
How do I propagate Little Bluestem?
Little Bluestem can be propagated by division, stem cuttings, and seed.
