On a recent day trip to Maui, I wanted to see flowers and spend some time outdoors. I always seek out gardens when traveling, and this seemed worth the trip. It's a quick drive from Kula/Makawao area, further up the mountain. As others have noted, this is a private attraction and collection of plants from around the world. As it is, they have an entrance fee of $10/person, plus a gift shop to raise money to keep it in operation. I felt the cost was worth the visit; you could walk through quickly in just a few minutes, but we meandered slowly and spent about an hour here.
Parking is free and easy right at the visitors center. They have seating overlooking the valley below outside, with restrooms, the ticket counter, and lots of Maui-produced goods and souvenirs. You're also given a laminated map to help you explore. The building feels like it hasn't changed much since the 1960s, it has an old vibe.
The gardens are organized around a central paved road, with paths leading off on both sides, plus benches and gazebos throughout. Most things are clearly labeled with names and origin of the plants. Many flowers were blooming, so there was lots of colors to enjoy. Their collection is from all over the world, not just Hawaii. The koi pond had been recently repaired after it was damaged by flooding, so it's not yet fully developed.
If you're a fan of flowers and the natural world, it's worth a visit.
