Leymus Condensatus

Description

Leymus condensatus, also known as blue wildrye, is a perennial grass that belongs to the Poaceae family. Native to North America, this ornamental grass is highly valued for its blue-green foliage and upright growth habit. It typically grows to a height of 3-5 feet and a spread of 2-3 feet, making it an ideal choice for borders, mass plantings, and erosion control.

Taxonomic Information

Appearance

The foliage of Leymus condensatus is its most distinctive feature. The leaves are narrow and long, measuring up to 2 feet in length and 0.5 inches in width. They are blue-green in color and have a waxy coating that gives them a silvery sheen. The foliage is also highly aromatic, with a sweet, grassy scent that is appealing to many gardeners.

The flowers of Leymus condensatus are not particularly showy, but they are attractive nonetheless. They are borne on tall, slender stalks that rise above the foliage in late spring or early summer. The flowers are typically a light brown or tan color and have a feathery, almost fluffy appearance.

• Water: Leymus condensatus is drought-tolerant once established, but it will benefit from occasional watering during periods of prolonged dryness. Water deeply, but infrequently, to encourage deep root growth.
• Fertilization: Leymus condensatus does not require frequent fertilization. Apply a balanced, slow-release fertilizer in the spring if desired.
