In the "Aquarium" many species of Nymphaea are to be found, including "Nymphaea alba", "Nymphaea tuberosa" hybrids of "Nymphaea × marliacea", the multicoloured "Nuphar lutea" and "Nelumbum nucifera". Moreover, in the areas further in that are not submerged but humid nevertheless, one finds "Alocasia", "Colocasia", "Zantedeschia", while in a nearby pond, the so-called "laghetto", Egyptian papyrus "(Cyperus papyrus)" and other cyperaceae such as "Scirpus lacustris" and "Cyperus alternifolius" are absolutely thriving.
