Corydalis decumbens

Corydalis decumbens is a perennial herbaceous plant native primarily to Asia. It is characterized by its short stature and spreading growth habit, and it blooms with yellow flowers from spring to early summer.

## Growth Characteristics
- Growing Environment: It thrives in partial shade and prefers well-draining soil. It is best to avoid excessive direct sunlight.
- Size: It typically grows to a height of 10–30 cm.

## Propagation Methods
- Seed Propagation: After the flowers have faded, collect the seeds and sow them directly in the autumn or germinate them indoors in early spring.
- Root Division: It can be propagated by dividing the roots in early spring or autumn. This method is best performed during the plant's dormancy period.

## Cultivation Methods

 - Planting: Lightly scatter the seeds on the surface and lightly cover them with soil. 3. Watering: Avoid excessive watering and water consistently to prevent the soil from drying out.
