Forsythia viridissima Kumson

Newly introduced, this is an unusual Forsythia with masses of bright yellow flowers during March and April. As the flowers pass, the new leaves emerge pale green at first and maturing to deep green with a strong silvery veination like an inticate artwork, the effect is quite striking. By Autumn the green leaf colour changes to hues of purple (the silvery network of markings is retained) before the leaves fall to reveal the purplish young winter stems. A very different Forsythia, something of a curiosity that brings interest to the garden long after the flowers have faded.

Forsythia Kumson is a compact variety growing to 150cm tall and wide, this is a great addition to a shrub border and for brightening up dark corners with its long season of interest. Having a bushy and compact growth it could also make a good informal hedge or screen.

Forsythia is an easy shrub to grow, quite content in all soil types although excessivly wet situations are best avoided. Once established the shrubs need little maintenance other than an annual trim or prune in Spring after flowering.
