Blue Ridge Parkway - Ecology Along The Parkway

Ecology Along The Parkway

Flowering shrubs and wildflowers dominate the parkway in the spring, including rhododendrons and dogwoods, moving from valleys to mountains as the cold weather retreats. Smaller annuals and perennials such as the daisy and aster flower through the summer. Brilliant autumn foliage occurs later in September on the mountaintops, descending to the valleys by later in October. Often in early-to-middle October and middle to late April, all three seasons can be seen simply by looking down from the cold and windy parkway to the green and warm valleys below. October is especially dramatic, as the colored leaves stand out boldly and occur mostly at the same time, unlike the flowers.

Major trees include oak, hickory, and tulip tree at lower elevations and buckeye and ash in the middle, turning into conifers such as fir and spruce at the highest elevations on the parkway. Trees near ridges, peaks, and passes (often called gaps or notches) are often distorted and even contorted by the wind, and persistent rime ice deposited by passing clouds in the winter.
