-Runyon's Water Willow (Justicia runyonii)

Runyon's water willow are water-loving plants, which grow in wetlands and damp habitats. These plants thrive in the warm tropical climates of Africa, India, and the Americas. The shrimp-like flowers of many species in this genus explain the common name "shrimp plant", and are much-loved by butterflies.
