We’re excited to announce that the International Aroid Society is launching a new and improved website platform to better serve our members!

Please note:
All membership renewals through the current website | PayPal will be paused starting April 23, 2025. Any renewals scheduled after this date will need to sign-up again through our new platform once it goes live.

Our website address (aroid.org) will remain the same, so you’ll still be able to find us in the usual place — with a fresh new look and improved features.

We apologize for any inconvenience this may cause and sincerely appreciate your patience during the transition. We can’t wait to share the upgraded experience with you, including easier access, smoother renewals, and new tools built with members in mind!

Stay tuned for more updates coming soon!

What is an Aroid?

Aroid is the common name for members of the Araceae family of plants, sometimes known as the Philodendron or Arum family. The occasionally beautiful and often bizarre combination of spathe and spadix called the inflorescence, sometimes referred to as a "flower", is a distinguishing feature of all aroids.
