Pampas Grass vs Quaking Grass Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Pampas Grass
Cortaderia selloana
Pampas grass is a tall, perennial grass known for its feathery plumes that emerge in late summer and persist through winter. It is a robust plant, typically grown outdoors as an ornamental feature in gardens and landscapes. Its large size and aggressive spreading habit make it unsuitable for indoor cultivation. People grow it for its dramatic appearance and the striking visual interest it adds to outdoor spaces. The plumes are often used in dried flower arrangements.
Quaking Grass
Briza media
Briza media, commonly known as Quaking Grass, is a perennial grass characterized by its delicate, heart-shaped spikelets that dangle and tremble in the slightest breeze, giving it its name. It typically grows to a height of 30-70 cm. The plant features slender stems and bluish-green leaves. While primarily an outdoor plant, it is grown for its ornamental value, particularly in meadows, wildflower gardens, and dried flower arrangements. It thrives in sunny locations with well-drained soil. Indoor cultivation is challenging due to its need for full sun and specific temperature fluctuations.
