What Is The Most Common Ornamental Grass? Find 6 Best

1. Pampas Grass – A Popular Ornamental Grass

Pampas Grass (Cortaderia selloana) is widely known for its dramatic, feathery plumes that rise above tall green foliage. It is a favorite in many gardens and landscapes, particularly in areas like Texas, Arizona, and California, where it thrives in sunny conditions. This grass is highly adaptable and can grow in a wide range of USDA planting zones, from 7 to 11, making it versatile for many climates.

It prefers well-drained soil and full sunlight, making it an ideal choice for xeriscaping or low-maintenance landscapes. Pampas grass blooms in late summer and fall, offering visual interest during the hotter months when many plants are dormant. The silver or white plumes add an elegant touch to gardens, often used for cut flower arrangements or as a focal point in landscaping designs.

However, care should be taken to prevent it from becoming invasive in some regions, as it spreads rapidly in optimal growing conditions. In areas like Florida and Georgia, where it can grow without much intervention, Pampas grass has the potential to outcompete native species. Despite this, it’s a great choice for gardeners seeking bold vertical interest and an eye-catching display in their yards.

Pros:

• Low maintenance
• Tall, dramatic plumes
• Thrives in full sun
• Attractive in bouquets
• Drought-tolerant

Its graceful, arching form and soft, feathery flowers add an elegant touch to gardens, especially during the late summer to fall season.

This grass thrives in well-drained soils and full sunlight, and its ornamental value is maximized when planted in clusters or used in mass plantings. It’s ideal for borders, containers, and even as a ground cover due to its neat, compact size. Fountain grass is also relatively low-maintenance, requiring only minimal pruning and occasional watering, making it a favorite for gardeners who want beauty with ease.

The plant is known for its ability to tolerate drought, making it perfect for xeriscaping and areas that experience dry conditions. In regions like California and Arizona, Fountain Grass can handle heat and low water availability without sacrificing its vibrant appearance.

It’s well-suited for USDA zones 4 to 8, making it a good choice for states like Missouri, Georgia, and California.

Blue Fescue thrives in full sun and well-drained soils, requiring minimal care once established. Its striking blue color provides contrast against other plants and adds a cool-toned element to any landscape. During the summer, this grass produces delicate flower spikes, adding an additional layer of interest to the garden.

While this grass is drought-tolerant once established, it prefers a moderate climate and can struggle in excessive heat.

Miscanthus thrives in areas such as Georgia, California, and Florida, where it receives plenty of sunlight and warm temperatures.

Miscanthus is highly valued for its striking plumes that appear in late summer and fall, transitioning from pink to silver as the season progresses. This grass is also drought-tolerant once established, making it ideal for xeriscaping. It can be used as a backdrop plant or as a privacy screen, providing visual interest and natural seclusion to outdoor spaces.

One of the key benefits of Miscanthus is its versatility, as it can tolerate a range of soil types and growing conditions. However, it may need to be divided every few years to prevent overcrowding.

This grass can grow up to 5 feet tall and is known for its airy, upright form.

Switchgrass is a favorite in prairie-style gardens and naturalized landscapes, offering soft, delicate flower heads in the summer and a rich golden color in the fall. It tolerates both wet and dry conditions, making it a versatile choice for various garden settings. Its tolerance to heat and drought, combined with its ability to grow in poor soil, makes it a highly reliable grass.

While Switchgrass is generally low-maintenance, it may require occasional pruning in the spring to remove dead growth and keep the plant looking fresh.
