Velvet Bentgrass (Agrostis canina)
Velvet bentgrass, scientifically known as Agrostis canina, is a fine-textured perennial grass prized for its use in creating dense, high-quality turf, particularly on golf course greens.
Considerations for Pets and Children
- This grass is known for its fine texture and dense growth, which might be appealing to pets and children.
Taxonomy and Nomenclature
- Scientific Name: Agrostis canina
- Common Names: Velvet bentgrass, Velvet bent
- Family: Poaceae (Grass Family)
Distribution and Habitat
- Velvet bentgrass is a perennial grass species found growing throughout Europe.
- It is also considered native to the northeast region of the United States, where it can be found growing on older estates, parks, and golf course fairways.
Morphological Characteristics and Growth Habits
- It has the finest texture of all the bent grasses.
- Known for its fine texture and high shoot density, forming a unique velveteen turf surface.
- It is a low-growing, fine-textured perennial species.
- Compared to colonial bentgrass, velvet bentgrass has a less upright growth habit.
- Spreads via stolons, more aggressively than colonial bentgrass, but less aggressively than creeping bentgrass.
Ecological Role
- Under reduced nitrogen and water conditions, velvet bentgrass exhibits vigorous growth.
- Its dense sward helps prevent the invasion of Poa annua (annual bluegrass).
Cultivation and Use
- Primarily used on golf course greens due to its ability to tolerate close cutting.
- Requires similar upkeep and maintenance to Creeping Bentgrass.
- Needs reduced nitrogen and water conditions to thrive.
- Used in seed mixtures known as South German bentgrass in the early 20th century in the USA.
Varieties
- Vesper velvet bentgrass is a newer variety known for superior heat stress tolerance.
- SR7200 is a velvet bentgrass variety released by Seed Research to meet the environmental needs of golf course professionals.
