Tropical Puff (Neptunia pubescens) is a short-lived perennial groundcover that produces yellow, showy flowers. It may grow 0.25 - 0.5 feet high and requires full sun with very dry lime rock or sandy soil with a high pH (calcareous). This plant with its interesting foliage and flowers will attract bees and butterflies. It is the larval host for the Ceranus blue butterflies.
