Pennisetum 'First Knight'

Pennisetum First Knight is a striking ornamental grass valued for its deep burgundy to near-black foliage and graceful, fountain-like habit. The narrow leaves arch outward, creating movement and texture in the landscape, especially when swaying in the breeze. During the growing season, subtle flower plumes may appear, adding softness and contrast to the dark foliage.

This grass works beautifully as a focal point in garden beds, mass plantings, or decorative containers. Pennisetum First Knight is especially effective in modern and contemporary landscapes, where its bold color can be paired with lighter-toned plants for dramatic contrast. It also performs well in mixed borders, adding depth and seasonal interest. Typically grown as an annual in cooler climates and a tender perennial in warmer regions, this ornamental grass delivers fast growth and reliable performance throughout the summer months.
