Winter Pampas Grass

Ornamental grasses include varieties such as winter pampas grass. Winter pampas grass features seed heads and foliage that add interest to the garden, especially in the winter when many other plants may lay dormant. A few pampas grasses work well year-round in milder climates where freezing conditions pose little danger to the plants. Winter pampas grasses require little maintenance although gardeners should consider growing native species; otherwise, introduced species may take over the area, eliminating native plant life.
  1. Coradeeria selloana

    • Coradeeria selloana, also known as fall flowering pampas grass, stays evergreen through the winter in mild climates in USDA hardiness zones 7 to 10. Clumps of the grass die when the ground freezes the soil down to the crown. Otherwise, while the leaves may look somewhat worn by spring, new leaves appear as soon as temperatures warm up again. The grass grows up to 5 feet in height, with stiff, arching leaves. The perennial plant grows larger each year, building up to a crown that can reach 5 feet or more across. In the fall, long, silvery and feathery plumes shoot out the top of the plant, adding another 2 feet of height to the already-tall plant.

    Purple Pampas Grass

    • Also referred to as Andean pampas grass, purple pampas features bright green, serrated leaves that reach up to 5 feet in height. The grass grows in USDA hardiness zones 7 to 10. The perennial grass is a native plant from South America that flowers in late summer or early fall. The flowers consist of long plumes tinged with purple that reach up to more than 3 feet in height. The flowers appear on top of the leaves, adding even more height to the plant. Each flower head can produce up to 100,000 seeds. Gardeners need to keep an eye on any purple pampas grass they plant since it quickly takes over other areas of the garden. In the wild, the invasive grass can overrun native species of coastal shrub and grasslands, eliminating food and habitat resources for wildlife and birds while endangering the ecosystem in which it occurs.

    Dwarf Pampas Grass

    • For smaller spaces in the garden or where you want decorative grass in front of larger plants, consider growing dwarf pampas grass. Dwarf pampas grass grows up to 3 feet in height. The plant features medium-sized white plumes that bloom in late summer. For gardens in cold-weather climates in zone 5 to 7, choose hardy types of dwarf pampas grass that can thrive as a semi-perennial once the plant becomes well-established. In warmer climates, the grass adds visual interest and form all year round.
