I credit (or blame) the snow plow drivers for spreading the orange daylily throughout the country side. They dig into the dirt when plowing sometimes and deposit the dirt with its daylily roots further down the road with the snow. In a few years, the whole roadside is an orange blaze come summer.
Nyboy, I once was stunned to find dandelion seed for sail in a garden catalog. The description stated that they needed rich, well drained soil. I sat there watching the dandelions blooming between the cracks in the sidewalk and in the gravel driveway and wondered at that.
Some folks yearn for the flowers of their youth and those roadside daylilies are as nostalgic as lilacs and bridal wreaths to many.
