Choosing Between Warm and Cool season GrassesOrnamental grases are classified into warm season or cool season depending on when they are in active growth. Cool season grasses begin growth in late winter or early spring and by early summer they are flowering and their growth slows. Many cool season grasses could be considered 'all season' as they are often evergreen and look good all year. Warm season grasses start to grow much later when it gets warmer. Flowering doesn't start until late summer and they look fantastic late into the fall. Often the dormant foliage looks very attractive through the winter as well. When choosing grasses it is ideal to choose a blend of warm and cool season grasses. This will provide interest from spring to fall.

Ornamental Grasses and DeerSurprisingly, deer don’t appear to be the least bit interested in ornamental grasses. Many have sharp leaf blades that would probably cut their mouths. In fact, these ones (e.g.Miscanthus, Cortaderia, Saccharum) can be used effectively to shield more vulnerable plants. Why they appear to be uninterested in the others is a mystery. topSome grasses that make great cut flowers |
