Largeflower Pusley is a creeping perennial broadleaf weed that is also commonly called Large-flower Mexican-clover or Richardia grandiflora.
Largeflower Pusley roots at the nodes, which feature hairy, branching stems. Its leaves are typically hairy, growing opposite and tapering sharply to points at both ends with a petiole. Largeflower Pusley features whitish-colored flowers clustered at tips of branches, though plants growing in partial shade can produce darker flowers. Reproduction of this broadleaf weed occurs by seeds and stem fragments.
This problematic lawn invader can be found in the warm subtropical regions of the southern United States. Largeflower Pusley thrives in disturbed, sandy areas receiving partial shade to full sun. It is a low-growing broadleaf weed that can quickly infest grass in your lawn and landscaping.
Richardia grandiflora is a very difficult weed to control using cultural practices alone. Solid lawn-mowing and watering practices are not enough to discourage the invasion, and physical removal (i.e., pulling weeds) often disrupts the plant's seeds, spreading the weed to additional areas of your lawn and landscaping. Professionally selected and applied broadleaf weed killers—based on your specific climate and geography—are the most effective method for control.
