The garden has a number of water features, including a buried cistern for the garden's water supply. The city of Oaxaca doesn't have enough water for the population, so the garden has a huge buried cistern, so it can be independent. Many of the plants are never watered, except for rainfall, but some plants require supplemental water, especially in the nursery area. The garden has a number of different areas: tropical plants, trees from arid areas, succulents, etc.
There are many succulents in the garden, but most of them were cacti. I am starting to like cacti more than before I moved to Mexico, but I like the spineless succulents much better.I liked the blossomng plants the best. I was surprised to see plants I think of as Hawaiian orgininaly came from the Oaxaca area. According to our tour guide, Oaxaca state was the origin for many many plants now growing all over the world.
