Sporobolus wrightii - Giant Sacaton

Compared to Sporobolus heterolepis, Giant sacaton is both much larger and quicker to grow. An established plant can easily reach 180+cm (6-7') every year. I planted plugs of this grass in late May and by fall the blooming height for most was 120-150cm (4-5') - from a plug! Seldom do we see such quick growth.

S. wrightii grows both tall and wide and given that the flowers are also large and architectural, it is a great plant to quickly fill a large area.
