This beneficial weed can be used as a companion plant to crops. Like most members of the umbellifer family, it attracts wasps to its small flowers in its native land; however, where it has been introduced, it attracts only very few of such wasps. This species is also documented to boost tomato plant production when kept nearby, and it can provide a microclimate of cooler, moister air for lettuce, when intercropped with it.
However, the USDA has listed it as a noxious weed, and it is considered a serious pest in pastures. It persists in the soil seed bank for two to five years.Temperatures were in the mid to upper 80s, humidity not too terrible, mostly sunny with a few puffy clouds.
