â€œThe summer flowering episode is my favorite, particularly in the mountain region,â€ says Adams. â€Beginning around mid-July and lasting into September, the roadsides become an exciting hodgepodge of vivid yellows, purples, and reds.â€ The flowers that Adams describes are summer wildflowers. Spring wildflowers have plenty of sunshine to grow in, but the summer ones must compete for the light. This makes them grow tall, big, and in thick clusters. Such growth makes for good viewing of their blossoms either on road shoulders or in adjoining fields. He describes wildflower viewing in the following areas: Blue Ridge Parkway, Great Smoky Mountain National Park, Ashe and Alleghany Counties, U.S. Highway 19, and Nantahala and Pisgah national forests.
