Abeliophyllum
The white forsythia (Abeliophyllum) is a deciduous shrub from the mountains of Korea, closely related to forsythia within the olive family. It is loved for its very early flowering: at the end of winter, before the leaves appear, the bare stems are covered with small, almond-scented white flowers, a soft alternative to bright yellow forsythia.
Abeliophyllum distichum
Abeliophyllum distichum is the only species in its genus and has become very rare in the wild. It forms a loose, rounded shrub of about 1.5 to 2 m with slender, arching branches. White flowers, sometimes tinged pink and with an orange-yellow centre, open from purplish buds in February and March; the leaves grow in two neat rows and turn golden to reddish in autumn.
Esposizione e terreno
Flowers most freely in full sun but tolerates light shade. Plant it in fertile, moist but well-drained soil that is neutral to slightly acidic, and avoid compacted or wet spots, where the roots may rot. It is very hardy and copes with severe frost; only in exposed sites can late cold damage the flowers.
Potatura e cura
Prune every year straight after flowering, in March or April, as the flower buds develop on the new shoots; renewing some of the oldest stems every few years keeps the shrub compact and free-flowering. Water regularly after planting until it is well established. Otherwise it is trouble-free and needs little attention.
Utilizzo in giardino
Best planted in groups or in a mixed border where the late-winter flowering can be appreciated, rather than as a summer focal point, since the shrub is fairly plain after flowering. It combines well with yellow forsythia and early bulbs, suits a low informal hedge or a large pot, and provides cut stems for forcing indoors.
