GeneralitŠ°


group of fairly vigorous deciduous shrubs, originating in Asia. They have dark green lunar branches, small shiny dark green lance-shaped leaves. At the beginning of spring, striking golden-yellow flowers appear on the bare plant, with four lobes, which stand out particularly as they are among the first flowers to bloom. Not all varieties are used as bonsai, as they have branches that are not very mouldable; usually dwarf varieties are used, with smaller branches and leaves; a good variety is the Forsythia intermedia minigold, as well as the forsythia ovata tetragold, very early flowering.
