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.

Fertilization / Feeding: For maximum health & hardiness, we highly recommend POOPeas
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.
POOPeas may be used at anytime.
