Variety description
10 August 2026
The plant has a dense, thick, conical crown shape. The needles have a rich dark green color and do not acquire a bronze tint during the winter period. Under favorable conditions, the tree can reach 30–50 meters in height, with a growth rate slower than that of the wild species.
The variety has increased resistance to fungal diseases, in particular, it is less susceptible to Botrytis infection. Due to a powerful taproot system, the tree is resistant to strong winds. Frost resistance is estimated at down to -29 °C (USDA zone 5).
The tree retains its lower branches for a long time under sufficient lighting. In conditions of insufficient light, the lower branches may drop, revealing the reddish-brown bark.
