Princess Caroline - Napier Grass

Princess Caroline™ is a vigorous ornamental Pennisetum hybrid with brilliant purple foliage and a sturdy habit. Its larger stature and broad leaves make it a dramatic focal point for sunny borders and large containers. ## Garden Use The exact [Emerald Coast Growers listing](https://ecgrowers.com/pennisetum-princess-caroline-38/) identifies Princess Caroline™ as Pennisetum hybrid ‘Tift 17’, PP21464, and lists a mature height of 60 inches, red seedheads, full sun, and USDA Zones 7–11. A [Royal Collection growing guide](https://www.growertalks.com/Article/?articleid=22968) describes a 4–5-foot spread and brilliant purple leaves that arch more broadly than Princess. The plant was developed by Wayne Hanna at the University of Georgia; the [patent application](https://patents.justia.com/patent/20100212053) records its formal designation and grant number. ## Seasonal Interest Warm light and summer heat strengthen the deep purple leaf color. Place it where the foliage can be seen against lighter plants, and allow room for the mature clump. ## Maintenance Water during establishment and extended dry weather. Remove frost-damaged foliage after winter in colder locations.
