Juniper don't usually have flat foliage pads. Chamaecyparis and Thuja both have flat foliage pads. Not sure what is popular in Spanish gardens but I'm guessing Chamaecyparis is much more likely. there are a few species and most of those have numbers of garden cultivars with many different foliage colors, sizes and shapes, often very different from the original species so can be hard to Id accurately.
