Diffuse Knapweed
Flowering heads are numerous and narrow. Flowers are white to rose or sometimes purplish. Margins of the bracts are divided like the teeth of a comb, and bracts are tipped with a definite slender spine. Diffuse knapweed infests roadsides, waste areas and dry rangelands, and as a highly competitive plant, threatens to exclude may desirable species. Flowering occurs from July to September. |
