With few exceptions, the entry into China, from which glycine comes from, was forbidden to Westerners until the late eighteenth century. In fact, the Wisteria sinensis was unknown to Europeans until a small number of British managed to enter the country for purely commercial reasons. Since then, throughout the nineteenth century, glycine has spread as a climbing plant in the gardens of Europe and the US, where it enjoys particular success with the Wisteria floribunda, in this case from Japan. The generic name of this species is dedicated to an American professor, Caspar Wistar. Glycine, as is also known, from the Greek glykis, meaning sweet. Very ornamental, ideal for pergolas and walls, spring is particularly striking to form large clusters of lilac flowers with butterfly shape that also give off a pleasant smell. The Chinese wisteria that covers the gallery of the Garden of the Galera from the Real Alcázar is a true example of bioclimatic architecture, since in winter it lets light and heat in, in spring qualifies the light with its flowers and intoxicating with its aroma, and finally in summer it reduces the heat input sifting mild light of the beautiful natural lattice formed by its abundant leaves.
