Other Names: Purple Fountain Grass, Elephant Grass
A durable ornamental grass grown for its burgundy-green foliage that intensifies to deep purple-black in summer; center leaves of the clump thrust vertical, outer leaves arch gracefully; will not flower in frost areas; ideal for massing or containers
First Knight Fountain Grass' attractive grassy leaves emerge grayish green in spring, turning burgundy in colour with pointy deep purple spines and tinges of black. As an added bonus, the foliage turns a gorgeous deep purple in the fall. Neither the flowers nor the fruit are ornamentally significant.
First Knight Fountain Grass is an herbaceous annual with a shapely form and gracefully arching foliage. Its relatively fine texture sets it apart from other garden plants with less refined foliage.
This is a relatively low maintenance plant, and is best cleaned up in early spring before it resumes active growth for the season. Deer don't particularly care for this plant and will usually leave it alone in favor of tastier treats. It has no significant negative characteristics.
First Knight Fountain Grass is recommended for the following landscape applications;
- Mass Planting
- Rock/Alpine Gardens
- General Garden Use
- Container Planting
Planting & Growing
First Knight Fountain Grass will grow to be about 4 feet tall at maturity, with a spread of 3 feet. Although it's not a true annual, this plant can be expected to behave as an annual in our climate if left outdoors over the winter, usually needing replacement the following year. As such, gardeners should take into consideration that it will perform differently than it would in its native habitat.
This plant should only be grown in full sunlight. It is very adaptable to both dry and moist growing conditions, but will not tolerate any standing water. It is considered to be drought-tolerant, and thus makes an ideal choice for a low-water garden or xeriscape application. It is not particular as to soil type or pH. It is highly tolerant of urban pollution and will even thrive in inner city environments. This is a selected variety of a species not originally from North America. It can be propagated by division; however, as a cultivated variety, be aware that it may be subject to certain restrictions or prohibitions on propagation.
First Knight Fountain Grass is a fine choice for the garden, but it is also a good selection for planting in outdoor pots and containers. Because of its height, it is often used as a 'thriller' in the 'spiller-thriller-filler' container combination; plant it near the center of the pot, surrounded by smaller plants and those that spill over the edges. Note that when growing plants in outdoor containers and baskets, they may require more frequent waterings than they would in the yard or garden.
