Nature Is Their Gardener Nurtured by deep humus and high humidity, both plants attain astounding size in the park. Rhododendron trees shoot up to 40 feet; trunks of the mountain laurel sometimes reach an extraordinary circumference. Brilliant pinks begin to tint the foothills in March. As spring progresses, flowers march up the slopes until in summer the heights blaze rose-pink (page 491). North Carolina's Wayah Bald and Tennessee's Mount Le Conte offered these sights late in June.
