Which Cryptomeria japonica variety is known as Plume Cedar?

The variety of Cryptomeria japonica known as Plume Cedar is indeed Cryptomeria japonica 'Elegans'. This particular cultivar is recognized for its distinctively soft, plume-like foliage that adds an ornamental aspect to gardens and landscapes. The leaves are typically needle-like, yet they have a feathery appearance, which contributes to the name "Plume Cedar." This cultivar thrives in a variety of conditions and is often prized for its lush, evergreen characteristics, making it a popular choice among horticulturists and landscape designers.

Other options do not relate to Cryptomeria japonica or the name Plume Cedar. For instance, Chamaecyparis nootkatensis 'Pendula' refers to the Nootka Cypress, which is a different genus entirely. Similarly, Abies procera is the scientific name for the Noble Fir, and not related to Cryptomeria japonica. The other Cryptomeria cultivar mentioned, 'Sekkan-sugi', has its own unique attributes but does not share the same common name as 'Elegans'.
