Forsythia koreana ‘Kumson’ stands out as a distinct variety within the Forsythia genus, known for its unique and stunning variegated foliage. Native to Korea, this particular cultivar is celebrated not just for the bright yellow flowers typical of Forsythia in early spring but also for its leaves, which display a beautiful combination of green with intricate white veining. This veining gives the leaves an almost silvery appearance, especially from a distance. As the plant matures, these veins can take on a light golden hue, adding another layer of interest to the plant’s appearance.

‘Kumson’ maintains a medium size, growing to heights of about 4-6 feet. Its upright and arching branches can spread equally wide, creating a mounded form.

Besides its ornamental appeal, it offers good winter hardiness and is fairly low-maintenance. Whether planted as a specimen or within a mixed shrub border, ‘Kumson’ ensures multi-seasonal interest, transitioning from radiant blooms to uniquely patterned leaves.

  • Grows up to 4-6 ft. tall and wide (120-180 cm).
  • A full sun or part shade lover, this plant is best grown in moist but well-drained soils. Best flower production is obtained in full sun. Some drought tolerance once established.
  • Perfect as a specimen plant, for foundations or hedges, in mixed borders, on banks or slopes. Great for cottage gardens.
  • Low maintenance, this plant is deer-resistant and relatively trouble-free.
  • Pests and Diseases: Forsythia is seldom troubled by pests. However, it may be affected by aphids, spider mites, four-lined plant bugs, or Japanese weevils. Forsythia is susceptible to leaf spot, twig blight, and crown gall.
  • Prune after flowering to maintain good form.
  • Propagate by semi-hardwood cuttings.
  • Forsysthia koreana is native to Korea.
