The collection of labiates is arranged on two dry-stone terraces, evoking a traditional construction technique that has been used since Prehistory and is currently in decline. This design, in addition to being an example of architectural integration with the natural environment, fulfils practical functions by preventing landslides, flooding and erosion. It also promotes biodiversity, which thrives in the crevices between the stones, and creates optimal microclimates for the development of these plants. For all these reasons, these terraces are not only a tribute to ancient practices, but also a sustainable and functional resource that enhances the botanical experience.

The family of labiates, also known as Lamiaceae, includes small- to medium-sized aromatic shrubs with a notable presence in Mediterranean ecosystems. Their importance goes beyond the ecological sphere, as many of their species produce essential oils of high medicinal, culinary and cosmetic value, giving them significant economic and cultural relevance. These plants, often harvested and cultivated for distillation and for flavouring food, represent an essential part of the natural and traditional heritage of the Mediterranean, while also contributing to its landscape identity.

This collection showcases numerous species of labiates, with particular emphasis on the genera Hyssopus (hyssop), Lavandula (lavender), Salvia (sage), Origanum (oregano), Satureja (savory), Thymbra (Andalusian thyme), Thymus (thyme), Rosmarinus (rosemary) and Sideritis, which includes S. serrata, a species in critical danger of extinction and a local endemic species, exclusive to Tobarra (Albacete). The display brings together endemic species from the Iberian Peninsula, Ibero–North African and Mediterranean taxa, highlighting the botanical richness and the value of this group of plants.
