We literally live in a town where the train for Weyerhaeuser goes by at least 15-20 times a day. Across the field from our backyard, is the actually train tracks the trains commute on back and forth. They do get quite annoying at times, but we have started noticing something from spring until the end of summer. The California Poppies (Eschscholzia californica) seem to love the tracks and grow wild along the steel beams. It almost makes the train tracks bearable just to see the poppies growing.
The California Poppy got its name because of growing as a wild flower in California. Living in Oregon, it just seems right that it would eventually make its way up north.
