David Bright said the perennial Miscanthus would offer keepers and shoot managers "tangible savings" over its long lifespan.
Bright said the plant's estimated productive lifespan was between 10 and 20 years, an increase on some of the more traditional gamecover crops.
"Miscanthus has a high value as a gamecover crop and nursery for young pheasants and partridges," he said.
"It makes good economic sense for shoots to invest in a crop that is easy to establish, requires minimal maintenance and will last for many years."
The Salisbury-based seed firm said the plant's height and root structure offered good cover for birds, and it was pest-free so needed limited attention.
Miscanthus was imported from East Asia 25 years ago, there are now 70 different types of the plant, he said.
