At the end of 1985, the garden opened its doors to the general public through guided visits. The narrow romantic-styled passageways ideal for strolling along the palace were repaired and an expert botanist carried out the first scientific classification of all the species and then arranged the plants around the garden.
Afterwards, the garden area grew 5 hectares arranged in several terraces with some slopes, although most species are distributed around the flattest area of the garden.
Nowadays, there is a great diversity of plants, trees and, above all, palm trees, which thanks to the climate of the island of Gran Canaria have adapted and developed. There are species of very valuable plants such as several dragon trees that are more than two hundred years old. At present, the Jardín de la Marquesa has about 500 classified species that live together with a colony of free-roaming peacocks.
