The Faial Botanical Garden has planted over 500 specimens of about 120 Azorean endemic species that make up its collection, including rare species such as Veronica Dabneyi and Myosotis azorica.

In addition, several other endemic species were planted, including: Myosotis maritima (15), commonly known as "Forget-me-not"; Leontodon filii (33); Azorina vidalii, known as Azores bellflower, (14); Euphorbia azorica (26); Pericalis malvifolia (17); Ammi trifoliatum (25); Solidago sempervirens, also known as seaside goldenrod, (26); Lotus azoricus (57); Cerastium azoricum (56); Scabiosa nitens (29); Tolpis azorica (45) and Tolpis succulenta (30).

These plants comprise several endangered species that are threatened by the disturbance and destruction of their natural habitats. Most specimens were grown in the rare plant nursery of Faial Botanical Garden, an infrastructure recently opened by the Regional Government with the aim of meeting the goals established by the UN World Strategy for Plant Conservation.

Being part of Faial Natural Park, the Botanical Garden is dedicated to the conservation of the natural flora of the archipelago through the Azores Seed Bank, the maintenance of threatened plants and the propagation of rare species, among other actions.

The garden, which is open to visitors, also contributes to the dissemination of the natural flora of the Azores and the knowledge on the biology of species.
