Morphology
Torreya grandis var. grandis represents a majestic evergreen tree that can attain heights of up to 39 meters under optimal conditions. Its trunk is covered in gray-brown bark that fissures longitudinally with age. The linear needles are flat, measuring up to 3 centimeters in length, and emit a characteristic aromatic scent when crushed.
The reproductive cycle relies on wind pollination of the unisexual cones. The resulting seeds are large, oblong-ovoid, and enveloped in a succulent, resinous aril. The hard inner shell protects a highly nutritious kernel rich in lipids and proteins.
Applications
Cultivators value this variety primarily for its edible seeds, known commercially as fragrant Torreya nuts or Xiangfei. These seeds are roasted and consumed as a premium delicacy in eastern Asia. The extracted seed oil is used in cooking and traditional cosmetics.
Additionally, the durable timber is prized for making chessboards, structural beams, and carved artwork. Traditional Chinese medicine employs the seeds to treat digestive disorders and eliminate intestinal parasites.
Interesting facts
Individual trees of this variety can live for over a thousand years, with several ancient specimens in Zhejiang province protected as living national monuments. The Kuaijishan ancient Chinese Torreya forest has been recognized as a globally important agricultural heritage system. Its seeds require two full years to mature, meaning that flowers and ripe fruit coexist on the same branch.
