What is an Aroid? 

Many of the most popular collectable plant species in the rain forest are aroids.

Aroid is the common name for the 3300 plant species which are members of the family Araceae.  Aroids include all Philodendron, Anthurium, Alocasia, Spathiphyllum (Peace Lilies), Colocasia, Calla Lily, Caladium, Amorphophallus and many other exquisitely spectacular species. The beautiful and often bizarre combination of ornate foliage with the production of an inflorescence known as a spathe and spadix distinguishes an aroid species.  Aroids are among the most loved and frequently grown house plants in the world!

Dedicated to collectors and the science of the plants we love, the International Aroid Society is over 32 years old and it's journal Aroideana is scientifically recognized.  The goal of the IAS is to support the preservation and scientific study of the species we grow but make the information available to any plant enthusiast.  Your IAS membership will support the study pf the world's delicate rain forest habitats as well as the introduction of species previously unknown to both science and plant collectors.  The IAS and its membership can also assist collectors to locate unusual specimens through a variety of resources.
