You'll find this Orchid nursery on the way to Volcanoes National Park. I'm sure it's not really off the beaten path, but it was a wonderful place to stop off at and dream of owning some of their beautiful orchid plants. They sell most of their potted plants, and most have already passed inspections and do not need to go through customs to leave the island. The nursery is in the back.
You can make an impression on your family&friends by sending them an orchid from Hawaii.
Be sure to go to the Akatuka Orchid Gardens and have a look.
You will want one of each. No kidding.
