Black Napier Grass, ‘Princess Caroline’ (Pennisetum hybrid ‘Princess Caroline’), is a striking ornamental grass known for its deep purple foliage and graceful, vase-shaped growth. Unlike traditional Napier grasses, this variety does not flower, making it an excellent choice for landscaping without concerns about self-seeding.
This cultivar was developed as part of Texas Superstar® Plants, a program that identifies and promotes high-performing plants suited for Texas landscapes. It was bred for its heat and drought tolerance, resistance to leaf spot, and vigorous growth. While the exact breeder is not widely documented, it was introduced to provide a low-maintenance, visually striking alternative to older Napier grass varieties.
Important cultural practices:
- Thrives in full sun
- Adapts to well-drained soils
- Drought-tolerant, but benefits from occasional watering
- Requires minimal fertilizer; excess nitrogen can cause leaves to turn green
- Hardy in most of Texas, but freezes to the ground in winter
- Pruning should be done in early spring to encourage fresh growth
- Commonly used as a specimen, accent in mixed borders, or as a quick-growing screen
Unlike many Napier grasses, ‘Princess Caroline’ does not flower, making it a non-invasive option. Its purple foliage deepens in hot summer temperatures, creating a dramatic visual effect, and it is resistant to common leaf diseases, making it a low-maintenance plant.
The Black Napier Grass, ‘Princess Caroline,’ is a heat-tolerant and drought-resistant ornamental grass with deep purple foliage that thrives in warm climates. It is non-invasive, disease-resistant, and easy to maintain, making it a fantastic choice for landscapes.
