Cryptomeria japonica 'Sekkan' / Sekkan sugi Japanese cedar

Cryptomeria japonica 'Sekkan' is a medium-growing, broadly-pyramidal tree-form of Japanese cedar. Foliage is a striking sulfur yellow, creating a focal point in the landscape. In young specimens, this trait makes them prone to sun scorch, but this becomes less of an issue as the plant matures. Typical rate of growth in most areas is 12 to 15 inches (30 - 35 cm) a year, resulting in a bold 12 foot (3.5 m) tall by 3.5 foot (1.5 m) wide statement in the landscape.

This is an old cultivar that originated in Japan. It is believed that Hillside Nursery of Lehighton, Pennsylvania made the American introduction around 1970. Like many cultivars of Cryptomeria, 'Sekkan' is often seen listed with the redundant term, "sugi" attached to the name (Cryptomeria japonica 'Sekkan-sugi'). This is how it is incorrectly registered in the RHS plant database. Sekkan means yellow in the Japanese language.
