Plant apparently native to China, the Oriental Arborvitae is widely distributed in the East, Manchuria, eastern Russia, Korea, Japan, India and Iran.
the Oriental Arborvitae is used in many parts of the world in the development of hedges. As in the gardens of the Real Alcázar can be found myrtle or boxwood hedges, there is also a significant presence of hedges from Oriental Arborvitae in the configuration and also two emblematic spaces. One of them is the Labyrinth, opposite to the Pavilion of Charles V, whose design is not far from the geometric drawing, of labyrinthine structure, which mysteriously appears on a slab paving the same Pavilion. The new maze was made around 1914, with myrtle, cypress and Oriental Arborvitae, to replace the one developed in the Habsburg era that was in the current Garden of the Cross and had disappeared shortly before, in 1910.
The other significant area of the Real Alcázar where the Oriental Arborvitae is used in shaping hedges, is the Garden of Poets. Designed by Xavier de Winthuysen between 1956 and 1958, this garden is organized around a sheet of water around which the hedges of Oriental Arborvitae are distributed. The Poets Garden is an initiative of the Alcázar curator who belonged to the Generation of 27, Joaquín Romero Murube, in an attempt to sum up in one space, the different types of historic gardens of the Real Alcázar. The Poets Garden is thus a synthesis that helps to establish what it is known as Seville garden: synthesis of Islamic, Renaissance and Romantic influences.
