The climatically favorable south wall of the sandstone building of the university library offers an optimal location for plants that prefer warm conditions. Among them are some aromatically fragrant, small shrubs from the Mediterranean region, such as the hemp palm (Trachycarpus fortunei) and other plants:
- Fig tree (Ficus carica)
- Cypresses (Cupressus sempervirens)
- Bitter orange (Poncirus trifoliata)
- Cistus (Cistus)
- Kermes oak (Quercus coccifera)
In between these, you will find grasses and herbs of the Mediterranean macchia and southern steppe.
