the genus abeliophyllum includes a single species, it is a shrub of small size, with deciduous leaves, originating in Korea. It has thin elongated stems, erect or slightly pendulous, brown or pinkish-brown; with roundish habit, these shrubs have slow growth, and can reach 150-200 cm in height and in width. The leaves are oval, sprouting after flowering, are green or bluish-green; sometimes they become purple before falling. At the end of winter, in January-February, it produces many white, star-shaped, slightly pendulous, very fragrant flowers; the buds are often present on the plant starting in September; there are cultivars with pink flowers, of various shades. This shrub is very reminiscent of the forsythia, but has smaller dimensions and very fragrant flowers, which bloom a few weeks before the forsythia. To maintain a harmonious shape of the shrub it is good to prune old branches every 2-3 years, at 20-30 cm from the ground. Those who love cut flowers can prune some abeliophyllum stems in January and force them to bloom indoors.
The white forsythia plants should be planted in a sunny place, or in partial shade, in a place where they can receive some hours of direct solar radiation, preferably in the afternoon hours.
These plants do not fear the cold, they can resist without difficulty at cold temperatures, but they do not tolerate the sudden late frosts, followed by hot days, which can cause serious problems to flowering.
The plants of white forsythia are generally satisfied with the rains, which are often quite abundant during the flowering period, since it occurs in the winter season, before the appearance of the foliage; in case of prolonged periods of drought it is advisable to water the plant, especially if it is a young specimen.
In autumn it is good to bury at the base of the plant well-mature organic fertilizer, or of universal granular fertilizer.
Abeliophyllum develop without problems in any soil, preferring well-drained, soft, rich and deep substrates. When white forsythia is planted, it is good to prepare a soil composed of peat, organic substance and pumice, so as to give the plant a well-drained substrate and avoid the formation of dangerous stagnation of water.
The multiplication of white forsythia usually occurs by cuttings, which must be taken from the tips of the stems, at the end of summer, or in late summer if there is a suitable place for the development of cuttings even in very hot climates. If you proceed at the end of the summer it is good to have a suitable space to allow the correct rooting of the new plants, before they are permanently placed.
