Here are some of the fruits which are currently visible in the greenhouses. The fist image is of a decorative pepper. It's tiny and not all that impressive but I still find it to be nice nonetheless.
The next two images are of the small cactus, Mammillaria. The images are from two different plants that both look slightly different. The first one seem to have longer fruits whereas the second has rounder ones. I'm not sure if maybe one has more mature fruit or if they are two different species/subspecies.
