This little attraction is nicely done, and appears to be still under development. Atop a steep driveway is a modest set of gardens centered by an outdoor diner / gift shop. The ice cream is mixed to order, and there are many shady tables with fantastic views of Opunohu Bay. There was no tour the day we visited, but strolling is nice enough. We wished for some labels on some of the plants. There are nicely built paths that criss-cross around the main buildings, and everything is well irrigated. Next to a fishpond is a screened vanilla "greenhouse" with plants in various stages of development. You can see all this in about half an hour.
I recommend venturing into the jungle where a narrow path has been cut along a stream. You may have to stoop and wade and scramble a bit, but at the top is a nice waterfall tumbling down Mt. Rotui.
On the other side of the driveway is a long orchard that is off limits. A new dwelling is under construction at the top of the property. I see this as a work in progress, worth a visit for the snacks and view alone - and there is no entry fee.
