In the "Settore Sperimentale e delle Piante Utili" (Experimental zone and zone of practical plantings) plants which produce foodstuffs are exhibited, such as sugarcane "(Saccharum officinarum)" and "(Sorghum saccharatum)", both used for the production of sugar; avocado "(Persea americana)", various cultivars of banana ("Musa acuminata × balbisiana"), pecan nut, not to mention an extensive collection of vegetable plants with over 100 cultivars of great historical interest and hugely important in terms of the conservation of a local gene pool. Lastly we have the medicinal plantings, including "Artemisia absinthium", "Datura stramonium", ginseng ("Withania somnifera"), la camphour ("Cinnamomum canphora") and the opium poppy ("Papaver somniferum").
