Visitors, and beginner, novice and experienced growers are all welcome.

The Cape and Islands Orchid Society (CAIOS) is a hobby group for orchid lovers on Cape Cod and the Islands.

Visitors, and beginner, novice and experienced growers are all welcome. We are social and chatty, sharing food, our successes & our failures.

Members bring in blooming orchids for our Show Table every month so you get to see dozens of blooming orchids each month, we have a small raffle and you can win orchids to experiment with, and many of our speakers bring plants to sell so you have an opportunity to purchase high quality orchids you will never see in a big-box store.

There are many benefits to joining the Cape and Islands Orchid Society:

  • Monthly meetings
  • Monthly newsletters
  • Free admission to our annual show
  • When you become a member, you join a community of fellow orchid growers
