Buffalo Bur Solanum Rostratum
The yellow flowers of the Buffalo Bur are similar to those of its near relative, the potato. They grow on bushy plants, 1-3 ft. high and are found along roadsides, in fallow fields and pastures at 4000-6000 ft. They bloom throughout the summer and the prickly pods are found along with the flowers. The common name refers to the prickles on pod and stem, and the specific one to the curious beak of the flower. The Buffalo Bur is an annual and hence it can be easily gotten rid of by cutting or burning.
