12 Most Popular Grass Types for Wild Prairie Gardens

by Flower El

Wild prairie gardens are a good replacement for lawns. A popular gardener once said: “A garden looks not enough natural and romantic without ornamental grasses.” He was absolutely right. Today, using grasses opens the new horizons for landscape gardeners.

Almost all the ornamental grasses are tufted perennial with narrow leaves and panicle form inflorescences. These plants may have underground stems with shoots or form tufts and clumps.

1. Miscanthus

Miscanthus (lat. Miscanthus sinensis) is also named as Chinese or Japanese Silvergrass and Maiden Grass. It is very popular in Japan, so can be used for prairie-style garden and for Japanese-style as well. Miscanthus is native to eastern Asia.

This grass is considered an iconic plant which blooms late in summer, often in August. In that time, the top of the tall (up to 6 ft (1.8 m)) stems are decorated with often purplish flowers gathered in tassel-like inflorescences. Its flowers can be used as cut and dry flowers.

Miscanthus grows very fast and may form clumps. It keeps its beauty all the four seasons.

Seeds are started in a cold frame in spring. You should divide seedlings in young age, because it can be difficult to do later.

Good-looking varieties of Miscanthus:

  • ‘Variegatus’ has attractive many-colored leaves.
  • ‘Kleine Fontane’ has the narrow arching leaves with white midribs. In fall, leaves turn yellow, red flower heads turn silver.
  • ‘Graziella’ is a German selection. Its flowers are silvery-white with a touch of pink.
  • ‘Silberfeder’ is one of the cold tolerant varieties of Miscanthus. It is tall up to 6.5 ft. (2 m) high.
  • If you live in areas with warm winters you should try ‘Gracillimus’ – a very beautiful variety with an elegant form and narrow leaves.
  • For those, who like originality, I recommend ‘Zebrinus’. This plant has striped leaves. It gives copper-colored flowers in September. It is tall up to 7.2 ft. (2.2 m).
  • ‘Morning Light’ is one of the oldest varieties known from 19 century. It is middle sized, grows up to 5 ft. (1.5 m). The plant gives pinkish flowers in September. This variety can grow near the ponds.
