Ball clover is a low-growing annual or short-lived perennial clover that thrives in average garden soils with moderate moisture. It is valued as a cover crop and green manure due to its nitrogen-fixing ability, and it produces small white flower heads that attract pollinators. It requires minimal care and is well suited to meadow plantings or lawn alternatives.
