PLACEMENT & CULTIVATION
Giant needle grass is a statuesque grass that develops striking seed heads with large teardrop seeds which dry to a honey gold color. The seed heads are spectacular when backlit by the afternoon sun. A native of Spain, Stipa gigantea is drought resistant and does well in regular soils; rich soils will encourage weak stems. Sharp drainage ensures winter survival. Iin early spring, prune close to the ground before new growth emerges.
Keep moist until established, then water during dry spells
Not particular about soil pH.
Mix in a few inches of compost prior to planting and top-dress yearly in spring thereafter, if desired.
Diseases & Pests:
Avoid fungal problems with proper spacing and by growing in a location with good airflow.
When to Cut for Bouquets:
