About Short-stalk Sophronitis

Sophronitis brevipedunculata · also called Dwarf Sophronitis · tropical

Sophronitis brevipedunculata is a miniature Brazilian epiphytic orchid bearing vivid scarlet to orange-red flowers on very short stalks. It grows best in cool, humid conditions with excellent airflow. ASPCA lists Sophronitis as non-toxic, making it safe in homes with cats and dogs.
