These pavilions display a collection of plants typical of the Mediterranean basin, including many useful plants. The decoration of the second pavilion is a constantly fruiting citrus grove and a large phoenix palm (Phoenix canariensis).
In the third pavilion, special attention is drawn to numerous large-sized palm trees, dominated by the rough palm (Trachycarpus fortunei). There is also a fig tree (Ficus carica), which is often covered with lush fruit. A special attraction of this pavilion is an approximately 10-meter-high cork oak (Quercus suber), which provides a valuable raw material from which bottle corks have been made for centuries.
The botanical curiosities of the pavilion include a group of coniferous plants (Podocarpus sp.), whose lanceolate or ovoid needles closely resemble the leaves of angiosperms. In Pavilion III there is one of the longest-growing plants in the Palm House, the European olive, Olea europaea, which survived the critical year of 1945.
