Neptunia pubescens 'pubescens'
Common Names: Sensitive Plant, Tropical Sensitive Plant, Hairy Neptunia, Sleepy Plant
Zones: 9–11
A low-growing, herbaceous perennial native to tropical and subtropical regions of the Americas, Neptunia pubescens 'pubescens' thrives in moist meadows, ditches, and disturbed sites from Florida to Central America. Known for its fern-like foliage that folds when touched and its yellow puffball flowers, it adds tactile interest and ecological value to native plantings and wetland restorations.
