Common Name: Horseherb (Horse Herb, Straggler Daisy, Lawnflower)
Latin Name:Calyptocarpus vialis; syn. Synedrella vialis
Family Name: Asteraceae
This perennial, low growing herb, with its small yellow flowers is native to Eastern Mexico and parts of the Southern USA, but also grows in parts of Latin and Central America and Australia. Although we can find no evidence of toxicity, there are some accounts of deer refusing to eat Horseherb, and so we advise feeding in moderation rather than feeding freely.
Young plants with no flowers are sometimes confused with Chickweed, so be sure of your ID.
