You can use tall grass or ornamental grass as screens, accents or focal points. If you can layout them properly, you will find out that tall grass are very attractive and give you more possibilities to create front yard landscape designs. Here are some ideas you can choose. Remember that maintenance in terms of mowing, pruning and watering should be done in regular basis.
To add privacy you can group tall grasses in a large group. They can be a perfect solution for screening an unpleasant view. For best effect, choose tall species such as big bluestem (it can reach 6 feet or more), moor grass (it can reach 7 feet or more), or Ravenna grass (it can reach 12 feet or more). Keep in mind that you will cut back ornamental grasses in early spring, so there will be a month or two while your grasses are growing that you will not have a screen.
Alternatively, you can use ornamental grasses to add unique texture to the landscape. Soft, mounding grasses such as fountain grass look great with plants that have a bolder texture, for example. More upright grasses, such as switch grass, make great textural counterparts to more mounded plants. To Maximize the effect consider planting several different grasses in the same landscape. Here fountain grass and a few varieties of miscanthus look great with black-eyed Susan, lavender, and hydrangea.
Consider using the tall grasses to dress up your deck or patio in back yard. Do not limit ornamental grasses to beds and borders in your landscape. Grow them in containers to add drama to decks and patios. Annual or tender grasses, such as purple fountain grass, are especially good choices for growing in containers because you need to replace them again in spring anyway.
Edging with greenery is one of attractive solutions given by tall grasses. Edge your beds and borders with a tidy line of neat grasses. Small selections, such as the blue fescue shown here, are best for this. Edging with grasses works best if you plant them a little closer together than you normally would so the grasses grow together in one line.
If you plant native grasses, you can invite wildlife especially birds to your garden. They will use the leaf blades for making nests, find shelter in larger grasses, and many species will eat the grass seeds
