Guide to cultivating characteristic plants in Baishan
Outdoor cultivation preferred varieties
Shrub species such as珍珠梅 (珍珠梅) and 红景天 (Rhodiola) that can survive at -30℃, combined with drought-resistant perennial plants like 萱草 (Xuancao) and 金鸡菊 (Coreopsis), form the main force in the courtyard. Early-flowering varieties of 牡丹 (Peony) and 芍药 (Chinese peony) should be chosen to ensure they complete their growth cycle before frost.
Indoor potted plant management essentials
Leafy plants such as 绿萝 (Green vine) and 吊兰 (Spider plant) are recommended to use double-layer insulation measures, starting to gradually control water from mid-October. Flowering varieties like 栀子花 (Gardenia) need to ensure 4 hours of sunlight per day, and window sill placement in winter should avoid direct cold wind, with night temperatures maintained above 12℃.

Cultivation characteristics of Rhodiola
As the city flower, Rhodiola has both medicinal and ornamental value. Its fleshy roots can withstand -25℃ low temperatures. During the flowering period from April to June, it is necessary to keep the soil slightly moist, and it is recommended to use a cultivation medium of mixed gravel and humus soil.
The city tree, Korean pine, has a history of thousands of years of growth in the Changbai Mountain area. Mature trees can reach 30 meters, and the phytoncides released by their needles have an air-purifying effect. Seedlings need to be shaded during the germination period, and 5-year-old seedlings can be transplanted outdoors.
By selecting plant varieties rationally and mastering key points of maintenance, it is entirely feasible to create an ecological courtyard with scenery all year round in the Baishan area. Rhodiola and Korean pine, as the city's calling cards, are worth focusing on cultivating and promoting.
