What is the common name for Picea abies 'Nidiformis'?

The common name for Picea abies 'Nidiformis' is Bird's Nest Spruce. This cultivar of Norway spruce is characterized by its unique, low-growing, and densely branched habit that forms a nest-like appearance, which is how it got its common name. The 'Nidiformis' variety typically exhibits a rounded mound shape and features short, soft needles, making it an attractive option for garden beds, rock gardens, or as a specimen plant.

In contrast to the other options, which refer to different plant species or cultivars, Bird's Nest Spruce specifically highlights the distinct structural form of Picea abies 'Nidiformis' and its appeal in landscaping design. Dwarf White is a more general term not specifically tied to the Norway spruce, Irish Yew refers to Taxus baccata, and Dwarf Mugo Pine denotes a variety of Pinus mugo, hence these options do not relate to Picea abies 'Nidiformis'.
