The leaves are divided into a petiole and a leaf blade. The petiole is 8 to 12 millimeters long. The simple and thin leaf blade is 5 to 7 centimeters long, ovate to broadly ovate, suddenly pointed with a slightly heart-shaped to truncated base and a finely serrate to almost entire leaf margin.
The light yellow flowers are solitary. The calyx lobes are broadly ovate. The corolla lobes are broadly elongated and longer than the sepal lobes. The stylus is short.
The Korean forsythia blooms from March to April.
The number of chromosomes is 2n = 28.

There are several cultivars and hybrids , including:
- 'Dresdner Vorfrühling' with broad, upright growth and densely branched branches. The flowers are light yellow and 3 to 4 centimeters wide, the branches are slightly square and hollow.
- 'Maluch', a hybrid of garden forsythia and Korean forsythia ( Forsythia ovata × Forsythia intermedia ), with compact growth, a height of 1.5 meters and numerous yellow flowers in groups of four.
- 'Northern Gold', a hybrid of Korean forsythia and European forsythia ( Forsythia ovata × Forsythia europaea ), with upright growth and a growth height of 2.5 meters and golden-yellow flowers that are singly or in groups. The hybrid is considered particularly hardy.
- 'Tetragold' with bushy, upright and compact growth. The flowers are deep yellow and 3 centimeters wide.
