PLANT DESCRIPTIONS & FACTS
Forsythia viridissima koreana 'Kumson'
An absolutely gorgeous forsythia that greets you in the spring with a brilliant display of yellow flowers like most all forsythias, but this variety also gives you beauty long after the flowers of early spring are gone. New foliage is a bright green, maturing to a deeper, more hunter green color with delicate silver veination all throughout the leaves. Looks like they have been painted!! A very vigorous grower - can be trimmed to maintain desired shape & size. Can take anything from full sun to almost full shade, and can withstand a wide range of soil conditions. Looks stunning when planted in groups, both in the spring, as well as all season long.

- 5 - 6 -
- 8 - 9 - 10 ] Highest Resistance
Fertilization / Feeding:
For maximum health & hardiness, we highly recommend
for use with all of our selections. However, either water soluble ( Miracle Gro, or equivalent ), or granular fertilizers ( Holly Tone is excellent ) are also good options. Most any granular fertilizers with a 6-12-12, or 10-10-10 ratio are also acceptable. Best to fertilize in early spring, and again in mid fall - avoid feeding standard chemical fertilizers during hot summer months, and directly after transplanting.
may be used at anytime.
Additional Features & Characteristics:
Needs Occasional Pruning:
This variety will need an occasional pruning to help maintain overall plant shape, and to control some branches that will grow much faster than the rest of the shrub.
