Forsythia x Intermedia 'Magical Gold' aka 'Kolgold'
Magical Gold ( 'Kolgold' ) Forsythia is a newer hybrid between weeping forsythia and greenstem forsythia, with x intermedia meaning that the hybrid characteristics are intermediate between those of the parents. Starts out in spring with a vibrant showing of bright yellow blooms
that are slightly larger than most commonly seen Forsythia varieties. One distinguishing feature of Magical Gold is the fact that these blooms form on BOTH old, and new wood. Blooming generally starts before any leaves actually appear on this shrub, but occasional will occur simultaneously with the arrival of new leaf buds. Magical Gold is one of the best, and most prolific flowering Forsythia varieties we have ever grown.
Leaves are 2 1/2" - 3" long, nice medium green color, and serrated around the edges.....especially towards the tips. Foliage remains nice & green all season, and takes on a yellow color in fall - can display some purplish color as well in colder climates in mid to late fall.
We generally recommend a yearly pruning of any Forsythia variety right after blooming has ended in spring. This yearly pruning will help keep a nice, tidy shape to the shrub, encourage good, dense branching habit, and will not affect the amount of blooms for the following spring. Pruning or trimming in summer, or later, will result in the removal of most flower buds & newer wood that would normally be used for flowering the next spring. This yearly pruning in spring after flowering is not as critical with Magical Gold, but still recommended for the other reasons mentioned above, and to maximize flowering capacity for the following spring.

Oftentimes Forsythia is the absolute first species in the landscape to
"wake up" from winter dormancy. Flowers generally last for at least 2-4
--Diseases / Insects :
serious problems, but the following have been noted to occur with
Forsythia on rare occasions: Crown gall, leaf spot, Japanese weevil,
northern root-knot nematode, and spider mites.
--Recommended Spacing :
3 ft apart recommended for typical hedge planting
--Deer Resistance Rating : Lowest Resistance [ 1 - 2 - 3 - 4 - 5 - 6 - 7 - 8 - 9 - 10 ] Highest Resistance
--Fertilization / Feeding :
For maximum health & hardiness, we highly recommend a good grade granular ( preferably organic ) fertilizer / plant food for use with all of our plant species. We personally use, and recommend the Espoma line of organic plant foods, as they are super effective yet gentle enough to use on even the most delicate of evergreen species where fertilizer burn would normally be a major concern. However, a water soluble type plant food (Miracle Gro, or equivalent ) are also acceptable options. Other granular fertilizers with a 6 - 12 - 12, or 10 - 10 - 10 ratio can also be used - but we suggest using them at 1/2 - 3/4 strength to avoid any chemical burn issues to the root system of the plants. Best to fertilize in early spring, and again in mid fall - avoid feeding standard chemical fertilizers during hot summer months, and directly after transplanting. The Espoma Organic Plant Foods may be used at anytime.
