Common Dandelion (Taraxacum officinale)

23 October 2015: While walking one of the trails at the Willamette Mission State Park in Wheatland, Oregon, we came upon a rather large Common Dandelion (Taraxacum officinale) flower which caught our attention and led us to photograph the specimen. The flower was nearly two inches across and it was larger than the other Common Dandelion flowers along the trail that we observed. Common Dandelion is not considered a native species to North America and is thus an invasive or introduced species but it is utterly widespread across all of North America and throughout the world according to the several sources we consulted for this posted observation (see Sources below). In any case, this particular flower was exceptionally large and we've seen Common Dandelion growing in several parts of the United States and Mexico in our lifetime by way of comparison. Common Dandelion is a world traveler and is found throughout the planet.
