Today, the editor will introduce the knowledge of when the seeds of February兰花 germinate and the best planting time for February兰花 in the field of green plants and flowers. Please see the detailed introduction below.
Cultivation and application of the herbaceous plant February兰花
1 Morphological characteristics
February兰花 is a biennial herbaceous flower of the Cruciferae, Osmunda japonica. It usually grows 20-70 cm tall. The whole plant is smooth and hairless, with a single stem or multiple branches. The leaves are large, the basal leaves are pinnately lobed, and the stem leaves are oblanceolate, with wavy serrated edges. The leaves are sessile, with auricles at the base, hugging the stem. The terminal raceme has 5-20 flowers. There are 4 petals, ovate, mostly blue-purple or light purple, a few white. The flower diameter is about 3cm. The blooming period is from March to May, with the peak period from March to April. There are still a small number of flowers in mid-to-late May. The fruit is linear, 6-9cm long, slightly tetrahedral. The seeds are ovate to oblong, maturing from April to June.

2 Ecological habits
February兰花 is native to Northeast and North China, widely distributed in North and Northeast China, covering various cities and provinces in the north. It has been promoted and applied in the provinces and cities of the Yangtze River Valley for many years, and has achieved satisfactory results. It grows naturally on flat land, near houses, or on small hills. It is strong, cold-resistant, rarely affected by diseases and pests, widely adaptable, and can maintain bright green throughout the winter. It is not strict about soil, and can generally grow in garden soil, as well as adapt to neutral or slightly alkaline soil. It grows robustly in fertile, moist, and sunny environments, and also grows well in shady and moist environments. Due to its strong self-sowing ability, it can also have good greening effects even on barren slopes and relatively dry places. It grows on flat land or under the shade of trees, where the leaf shape becomes larger or deeply lobed under the tree shade.
3 Cultivation and management techniques
February兰花 is easy to sow and can self-sow for propagation. It is usually propagated by seeds, has strong regeneration ability, and new plants can quickly grow from seeds that have just fallen after the plant withers. Seeds sown manually on unturned soil can also grow into seedlings and have strong resistance to weeds. Therefore, the cultivation management can be relatively relaxed.
Newly harvested seeds may have a post-ripening physiological phenomenon, with low germination rate for early sowing, and germination may last 1-2 months or even longer. The sowing time can be随时随采随播, but August and September are the most suitable. There are 300-400 seeds per gram, and it is best to use 500g per mu, or 1g/m2 if calculated by the area. If broadcasting by喷播方式, it is best to increase the dosage by 10-20% for the unit area.
4 Application in landscape greening
(1) February兰花 has elegant flower color and long blooming period, making it a good ground cover plant in spring. It is most suitable for planting under forests, forest edges, residential areas, slopes, or edges of grasslands. It can be planted alone or mixed with various shrubs such as榆叶梅,棠, etc., forming a spring scene with a wild charm.

(2) February兰花 can be widely used in parks, urban streets, expressways, or railway sides for greening. Large areas of blooming flowers create excellent greening and beautifying effects. In recent years, Beijing has used mechanical broadcasting for expressway slope greening, with even more ideal results. Using seeds from self-sowing, new seedlings can grow just as the previous generation of plants wither in mid-to-late June. Therefore, there is basically no bare ground in February兰花 ground cover, making it an extremely good plant material for expressway slope greening.
