Pseudotsuga sinensis seed

LATIN NAME: PSEUDOTSUGA SINENSIS

COMMON NAME: Chinese Douglas Fir

The Chinese Douglas fir tiers the tall, evergreen tree with the flat, soft, needle-like leaves that spread in the layered, tiered sprays along the branchlets and the small, pendent cones with the protruding, three-pointed bracts that ripen through the summer, the thick, fissured bark developing with the age. The crown rises in the elegant, layered form, and the tree stands the cool, moist mountain climate well. It likes the sun, and the deep, moist, well-drained soil.

Scientific Research & Plant Biotechnology

The layered sprays of the Chinese Douglas fir give it a recognised place in the research on the montane conifers of the warm-temperate forests, and the sinensis species appears in the studies of the tiered-crown development and the cone bract structure. The work looks at the way the crown rises in the layered form, the watershed cover on the mountain slopes, and the seed biology. The foresters value the timber, and the growers of the rare ornamental conifers keep the species in their catalogues.

Ecological & Economic Value & Wide Applications

In the cool, large garden, the Chinese Douglas fir tiers the cool garden with the layered green crown. The timber serves the construction and the joinery, the cone bracts add the interest, and the tree makes the fine specimen and the shelter. It thrives in the deep, moist, well-drained, sunny ground. Layered, stately and montane.

To grow the Chinese Douglas Fir from seed, sow the seeds into the leafy drills of the seedbed in the autumn, then cover them lightly, keep the bed moist and cool, and the young trees show themselves in the spring.

Keep the bed moist and cool, and give the young trees the open, sunny spot. The tiered crown comes over the years. Settle the young trees in the deep, moist ground, and the tiered crown will layer over the years.
