Here’s an overview of Pennisetum (fountain grass):
Plant Characteristics:
Foliage: Fountain grasses typically have narrow, linear leaves that are green or variegated, depending on the species and cultivar. The leaves may change color throughout the year, especially in colder climates during the fall season.
Inflorescences: One of the main attractions of Pennisetum is their showy and feathery inflorescences. These flower heads, or “plumes,” rise above the foliage in late spring or summer and persist into fall. The plumes can be pink, purple, white, or a combination of colors, depending on the species.
Growth Habit: Pennisetum grasses have clumping growth habits, meaning they form dense tufts of foliage. They generally have an arching or cascading habit, giving them a graceful appearance.
Size: The size of fountain grasses varies depending on the species and cultivar. They typically range from 1 to 4 feet (about 30 to 120 cm) in height.
Cultural Requirements:
Light: Pennisetum grasses prefer full sunlight, although some species can tolerate partial shade.
Temperature: These grasses are adaptable to a range of climates but generally thrive in warm and temperate regions. Some species are cold-hardy and can withstand freezing temperatures, while others are more suitable for tropical or subtropical climates.
Watering: Fountain grasses have moderate water needs and prefer well-draining soil. They should be watered regularly during the growing season, but they can tolerate some drought once established.
Soil: Pennisetum grasses grow well in various soil types, as long as the soil is well-draining. They can tolerate both sandy and loamy soils.
Fertilization: These grasses are generally low-maintenance and do not require frequent fertilization. A balanced, slow-release fertilizer applied in spring can help promote healthy growth.
