Does ornamental grass come back every year?

Answered by Jeremy Urbaniak

Most ornamental grasses are perennial plants, meaning they come back year after year. This is one of the reasons why they are so popular in gardens and landscapes. Unlike annual plants that need to be replanted each year, perennial ornamental grasses provide a low-maintenance option for adding beauty and texture to outdoor spaces.

As a gardener, I have always loved the reliability of perennial grasses. Once established, they require minimal care and can thrive for many years. This makes them a great investment for those looking to create a long-lasting and sustainable garden.

However, it’s important to note that there are a few ornamental grasses that are grown as annuals in colder northern climates. In areas where winters are particularly harsh, these grasses may not survive the cold temperatures and will need to be replanted each year.

If you live in a region with cold winters, it’s a good idea to research which ornamental grasses are best suited for your climate. Some popular annual grasses include Pennisetum setaceum (Purple Fountain Grass) and Panicum elegans (Fountain Grass). These grasses can add a burst of color and interest to your garden for one growing season but will not come back the following year.

For perennial grasses, proper care is essential to ensure their long-term survival. When planting ornamental grasses, it’s important to prepare the site properly. This typically involves digging a hole that is wider and deeper than the root ball of the plant. Adding organic matter, such as compost, to the soil can help improve drainage and provide essential nutrients.

Once planted, ornamental grasses generally require minimal maintenance. Regular watering is important during the establishment period, but once they are established, they are typically drought-tolerant. Some grasses may benefit from a light trim in late winter or early spring to remove dead foliage and promote new growth.

In terms of winter care, most perennial grasses can withstand cold temperatures without any special protection. However, in regions with extremely harsh winters, it may be beneficial to provide some insulation by mulching around the base of the plants. This can help protect the roots from freezing and ensure their survival.

While most ornamental grasses are perennials and will come back year after year, there are a few that are grown as annuals in colder northern climates. It’s important to choose the right grass for your climate and provide proper care to ensure their longevity. With their beautiful foliage and low-maintenance nature, ornamental grasses are a wonderful addition to any garden or landscape.
