Grass, Princess Caroline Napier

Warm season tender perennial grass that is winter hardy to USDA Zones 8-10. It is grown as an annual north o f USDA Zone 8. This grass performs best in medium moisture, well-drained soils in full sun. It appreciates consistent water throughout the growing season. It can be dug in fall, trimmed, and overwintered in greenhouses or indoors in sunny cool areas in cold winter climates, but many gardeners simply prefer to purchase new plants each spring. Tall plants may need some staking or other support and should be sited in areas protected from strong winds. When grown as a perennial, species plants can become invasive self-seeders. Species plants are not currently recommended for landscape use in warm winter areas where freezing temperatures typically do not occur prior to December 1 (USDA Zones 9-10) in large part because plants will flower, seed and self-seed invasively in such conditions. 'Prince' is reportedly nearly sterile, and therefore self-seeding is less of a concern. To the extent that 'Prince' may self-seed, the new plants reportedly will not come true.
