Phalaris arundinacea, more commonly known as Reed Canary Grass, is a tall-growing bunchgrass. It's often found beside rivers, streams, ponds and wetlands in its native habitat.

One of the most common cultivars of this species is Ribbon Grass (Phalaris arundinacea var. picta). This is an ornamental grass variety with eye-catching variegated foliage that can work well as a tall, textured and interesting ground cover.

Although Ribbon Grass flowers, it's the foliage that makes this plant. The blooms aren't of any great significance. This cool-season grass grows in the spring and fall but can go dormant during the summer months.

In sunny sites, with consistent moisture, this plant thrives. In fact, it spreads incredibly easily and quickly. For this reason, it won't be suited to every garden. Ribbon Grass can quickly overtake small spaces, and some states even class this species as an invasive and noxious weed. It will work, however, being grown contained in pots or being used as a dramatic mass planting option.

It can grow in wet, boggy conditions around ponds and can stabilize river bank edges or slopes. It's best to select it for those purposes when nothing else will grow. Otherwise, it could choke out other established species with its strong spreading rhizomes. This hardy grass can also grow in dry, desert gardens, and these conditions will limit its spread considerably. Ribbon grass is considered invasive in some areas, so check with your local extension office agent before planting it.

How to Grow Ribbon Grass

A versatile, robust plant, Ribbon grass will grow in most soil types and can also handle standing water or dry conditions. It's a low-maintenance species, and it isn't prone to disease or pest infestations.


This species is considered invasive in some areas of the country. Check with your local extension office agent before planting it.


Ribbon Grass thrives in partial shade locations. It can also cope in full sun, but if the summer heat is intense, then leaf scorch can occur. A partial shade location also means that the spread of this plant is less intense, and it's less likely to choke out other plants.


One of the advantages of Ribbon Grass is that it tolerates a wide variety of soils. It can cope in dry, infertile soils, clay and sand. It isn't fussy about pH levels either. The one thing it does like is for the soil to be well-drained.


Ribbon Grass prefers moist soils, but this robust plant can still survive in standing water and when conditions are dry. If you want to limit the spread of Ribbon Grass, keeping conditions drier can help. When you're using this species as a stabilizer or a fast-spreading ground cover, you will want to keep it well watered to encourage speedy growth.

Temperature and Humidity

This hardy grass can cope with a wide variety of conditions. As already mentioned, intense heat can lead to leaf scorch. Frost can also lead to damage to the leaves. It's a good idea to protect the roots with mulching in winter if you experience colder conditions.


Ribbon Grass doesn't need regular feeding to thrive. However, if your plants have suffered from leaf scorch during a hot summer, using a weak fertilizer solution can encourage new and healthy growth.

Propagating Ribbon Grass

While Ribbon Grass produces seeds, it spreads primarily through fast-spreading rhizomes. It's easy to propagate from these in the spring or fall. You can also create new plants by dividing healthy clumps in the spring.


To keep variegation, prune down to the new growth in the early summer. If the leaves become sun-scorched in intense sun, cut back the plant in mid-summer to encourage new growth for fall. Pruning also helps to retain the striking variegate pattern on the grass.
