Experimental Garden (Tiétar Valley, Spain) —2020

Planted in an old orchard with poor soil and too many rocks, this garden is where Álvaro tests the species he intends to use for clients: how much water they need, and how textures, colours and flowering times combine. Seven circles of crushed granite are surrounded by Iberian natives such as Pistacia lentiscus, Lavandula multifida and Armeria pungens, pruned lightly to echo the grazing of goats. Grasses (Panicum virgatum ‘Heavy Metal’, Muhlenbergia capillaris, Calamagrostis × acutiflora ‘Karl Foerster’) add movement and colour. The garden is also a showroom and a place to teach gardeners.
