It is a shame that forsythia is not more popular here. Years ago, there was a commonly perpetuated myth that winters were not cool enough for it, as well as lilac. We now know that both lilac and forsythia are happy to bloom here. Now, some might insist that there are so many evergreen shrubs that bloom nicely right through winter, that there is no need for deciduous blooming shrubbery.
They might not say so after seeing how spectacular forsythia is in bright yellow bloom as winter becomes spring. It uses the same tactic as the flowering cherries that bloom at about the same time, by dazzling spectators with profusion, before foliage develops to dilute the brilliance of the color! The flowers are tiny, but very abundant. Plump buds on bare stems can be forced indoors.
Forsythia X intermedia is the standard forsythia, although a few other specie and variations, including some compact cultivars, are sometimes seen in other regions. Mature specimens should not get much higher than first floor eaves, but can get twice as tall if crowded. The simple opposite leaves are about two or three inches long, and can turn color where autumn weather is cooler.
