If you enjoy succulents and cactus, this is the place to go. They have hundreds of well-established plants from different desert regions, all in good condition, some very large. There is also a greenhouse area where some of the plants are grown in pots.
The dirt paths are well maintained, and some of them might be wheelchair compatible. I had no trouble getting around with my cane. There are several benches to sit on. There is A Restroom, but I didn't look into it, so can't comment on it.
There is a big dirt parking lot about 1/2 block away, and street parking may be available. There is no sidewalk, so approaching the garden requires walking along the street or on a narrow dirt strip. The entrance is a rathe steep, but short, driveway - I thought it was too much for a wheelchair.
We saw and heard many hummingbirds here.
They have plants for sale, and they all looked healthy and attractive.
