Expert tips
The key tip
Schizachyrium scoparium is the dry grass par excellence: avoid watering it in summer, even in full sun. Its taproot system accesses deep moisture; regular watering will drown it.
The common mistake
Watering regularly or planting in soil that's too wet in autumn-winter.
The pro's trick
Cut it back hard in February-March before spring growth kicks in: you'll then see the young golden-bronze shoots emerge.
Seasonal watch
In autumn, its color turns to a sublime red-copper; don't cut it back before late February.
Care
Exposure
Little bluestem requires a sunny exposure (minimum 6 hours of direct sunlight). Place it in full sun to achieve beautiful leaf coloration and optimal growth. In overly shaded conditions, the plant weakens and takes on a sparse appearance.
Watering
This is a grass very resistant to drought. Water regularly during the first year to establish the root system, then gradually reduce. Once established, it only needs water during prolonged dry spells.
Soil
This grass adapts to all soil types, including poor and well-drained soils. It even tolerates sandy, rocky, or slightly acidic soils. Simply avoid overly compact soils or those constantly waterlogged.
Pruning and maintenance
Cut back to ground level (5 to 10 cm) in late winter or early spring, before growth resumes. This cutting rejuvenates the clump and removes dried parts. A light cleanup of dead leaves in autumn is sufficient if you wish to preserve the autumn appearance.
Fertilizer
No fertilizer is necessary. Little bluestem is suited to poor soils and actually appreciates minimal nutrient input, which strengthens its hardiness and self-sufficiency.
Diseases and pests
Very robust, this grass is rarely affected by diseases or pests. Proper drainage is enough to prevent any risk of rot. No special treatment is required in normal cultivation.
Did you know?
Little bluestem owes its name "scoparium" (broom-like) to pioneer America, where the fine and slender flower heads were actually used to make small brooms. Native to the North American Great Plains, this ornamental grass has become a symbol of ecological restoration: it helps regenerate degraded prairies and serves as a refuge for many pollinating insects.
Where to buy it
Plant in spring or early autumn, avoiding spells of intense heat. Pick a plant with healthy foliage and roots that are not exposed. Best time: March, April, May, September.
