Ornamental Grasses... adding interest to your late summer & fall landscape!

Some of the best late season, dramatic landscape scenes include ornamental grasses. 

Ornamental grasses can be used as borders, planted in small groupings, mass planted, or as a single specimen to add interest.

Most grasses are very adaptable to heat, drought and humidly.  They also grow in most soils.

There are both cool season and warm season ornamental grasses.  Cool or warm season refer to the time of the season they bloom.  Cool season start growing earlier in the spring and look stunning in early summer.  But, warm season grasses emerge later in the spring and add interest to the landscape as they flower in late summer to fall.

Ornamental grasses require little maintenance, needing attention only once per year.  Grasses do best if 1/3 of their dormant top is removed in early spring before new leaf blades emerge.

There are too many varieties of ornamental grasses to cover them all, but here are just a few favorites:
