Fun Facts

🌱 Hinoki Boulevard was selected in the 1960s and is a dwarf cultivar of the Japanese Hinoki cypress, which can grow much larger in its native habitat.
🌱 The purple-bronze winter coloration is a natural cold hardiness response; the anthocyanin pigments protect the foliage from winter sun damage and frost stress.
🌱 Despite its fine, feathery appearance, the foliage is soft to the touch and rarely causes skin irritation, making it safe for families with children and pets.
