Hardy Cortaderia Collection

Hardy Cortaderia Collection is a striking set of cold-tolerant pampas grass plants selected for strong growth, elegant arching foliage, and impressive, feathery plumes. These ornamental grasses create instant structure in the garden, adding movement and height to borders, mixed beds, and large containers. The collection is ideal for modern landscapes, prairie-style planting schemes, and as a dramatic focal point in sunny, open spaces. The tall plumes also dry beautifully for indoor arrangements, giving you decorative material to enjoy long after the garden season ends.

The plants typically reach 150–250 cm (59–98 inches) in height including the plumes and form substantial clumps with a spread of about 80–150 cm, depending on variety, maturity, and growing conditions. The arching green foliage provides year-round texture, while large feathery plumes (colour varying by variety) appear from late summer into autumn for a bold, architectural finish. For best results, plant in full sun in well-drained soil, as wet ground—especially in winter—can weaken plants. Water regularly during the first growing season to establish roots, then reduce watering once established; leave foliage standing over winter for protection and cut back in early spring before new growth begins (wear gloves, as the leaves can be sharp), and in colder or wetter regions add a winter mulch and ensure excellent drainage for reliable survival.
