Pennisetum ‘Fireworks’ is a colorful ornamental grass that brings both movement and contrast into the landscape. It’s known for its variegated foliage, with streaks of green, cream, and burgundy that shift in intensity depending on the season and light.

As it matures, the color becomes more pronounced, especially in warmer months when the burgundy tones deepen. The blades arch outward, creating a soft, fountain-like shape that adds a sense of motion even when there’s just a light breeze.

In late summer into fall, it produces fluffy, bottlebrush-like flower plumes that rise above the foliage. These add another layer of texture and catch the light nicely, especially when planted in groups.

It works well as an accent plant, in containers, or massed together for a more dramatic effect. The color variation makes it especially useful for breaking up more uniform plantings.

Pennisetum ‘Fireworks’ grows best in full sun and prefers well drained soil. It benefits from regular watering during the growing season to keep it looking full and vibrant.

It typically reaches about 3 to 4 feet tall and wide, forming a rounded, fountain-like clump. It is well suited for USDA zones 9 through 11 and is sensitive to frost. The foliage is perennial in mild climates but may die back in colder conditions. 

One thing to be aware of is that this variety can sometimes revert back to its parent form, which is a solid green grass. When that happens, it loses the variegation that makes it stand out. Reverted growth should be pruned out early to maintain the plant’s color.

This plant has low toxicity and is generally a safe choice for gardens with pets and children.

The flowers may attract pollinators and add seasonal interest.

It is generally deer resistant, though occasional browsing may occur.

Pennisetum ‘Fireworks’ fits especially well into tropical, modern, and container garden designs, where its color and movement can be used as a focal point or accent.

Expert Tip:

I like using this in spots where you want color but also movement. It’s great in containers or near patios where you can actually see it shifting in the wind. Just keep an eye out for any solid green shoots and cut them back early so the plant keeps that variegated look.
