Cortaderia

An excellent architectural focal point plant or screen for full sun on well drained soil with the added benefit of being deer resistant.

Cortaderia araucana

Cortaderia richardii ( New Zealand Pampas Grass )
Rarely grown in North America; this New Zealand native forms HUGE clumps with arching stems reaching up to 20 feet! The flowers plumes are white. It is native to swampy places and lowlands and prefers moist, sandy soil in full sun. Hardy north to zone 7

Cortaderia sellowana ( Argentine Pampas Grass )
Native to Argentina and commonly cultivated in the southern and Mid Atlantic U.S.
The Argentine Pampas Grass is among the most regal and stately of all ornamental grasses reaching up to 12 ( record is 20 ) x 13 feet with huge silvery-white plumes reaching up to 40 inches in length. The plumes look great against a dark background.
The arching, saw-toothed leaves, up to 9 inches in length, are glaucous blue-green.
The foliage is evergreen in mild climates but turns herbaceous in colder winter climates.
Hardy zone 7 to 10. It can survive zone 7 winters with the clumps tied up and the root zone mulches well but is not hardy farther north. Do not cut back until early spring. For zones 5 and 6 check out some of the cultivars below. Not only is it drought tolerant, but the Argentine Pampas Grass has invasive potential in dry summer Medeiterranean Regions of California, Europe and New Zealand.
Deer and rabbit resistant. Salt tolerant.
