Comments: A North American native, Erodium texanum, Texas Stork's Bill, is similar in appearance to Redstem Stork's Bill Erodium cicutarium but not nearly as common and Texas Stork's Bill does not bloom in large numbers every year. Conditions for good spring blooms are not fully understood but likely tied, at least in part, to winter rainfall.
