Sporobolus wrightii - Giant
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.
