Guelder-rose is a spreading, much-branched deciduous shrub, up to 4 m high, with greyish, hairless stems. The beautiful guelder rose is a spreading, bushy, asymmetrical shaped shrub. The 5-petalled, fragrant flowers are arranged in dense clusters with large sterile white flowers on the outside and small, creamy-yellow fertile ones called lace cap on the inside. They open in June and July. The maple-like, green leaves turn to stunning shades of red, orange and yellow in autumn. The large clusters of round, brilliant red and glossy - almost translucent - fruits remain on the plant throughout the winter and look particularly attractive against a background of snow.
The Guelder Rose prefers to grow at low altitudes and in semi-shade in Scotland and England. It is native to the woodlands of the European deciduous forest. Thus guelder rose is widely distributed in Europe, including Britain, from Scandanavia south and east to Spain, north and west Asia.
It is found in woods, scrub and hedges, especially on damp, lime-rich, soils. It is found at the edges of woods, hedgerows and marshes. In the United States it is found in agricultural zones which have a relatively cool climate. It grows in both heavy clay and acidic soil. This Shrub will grow well in a wide variety of loam or soils pertaining to most average garden situations, a pH which can apply to most normal garden soil conditions.
Seed is best sown in a cold frame as soon as it is ripe. Germination can be slow, sometimes taking more than 18 months. If the seed is harvested 'green' and sown immediately in a cold frame, it should germinate in the spring. Stored seed will require 2 months warm then 3 months cold stratification and can still take 18 months to germinate. Prick out the seedlings into individual pots when they are large enough to handle and grow them on in a cold frame or greenhouse. Plant out into their permanent positions in late spring or early summer of the following year. Cuttings of soft-wood, early summer in a frame. Pot up into individual pots once they start to root and plant them out in late spring or early summer of the following year. Plant them into individual pots as soon as they start to root. These cuttings can be difficult to overwinter, it is best to keep them in a greenhouse or cold frame until the following spring before planting them out.They should root in early spring - pot them up when large enough to handle and plant them out in the summer if sufficient new growth is made, otherwise keep them in a cold frame for the next winter and then plant them out in the spring.The bark is collected in April and May, cut into pieces and dried.
The conspicuous, large, nearly flat topped heads of snow-white flowers are in bloom during the early spring.
Pests and Diseases
The Guelder Rose can be an invasive shrub and therefore is definitely not threatened.Viburnum leaf beetles feed on many species of Viburnum in both adult and larval stages. The beetles are very damaging because of this successive feeding by larvae followed by adults; bushes do not have time to re-vegetate between beetle stages. Two or three consecutive years of defoliation can cause significant die-back of the canopy and kill a bush. It is also affected by a foliage diseases showing symptoms of variegation, light green to white patches, vein yellowing and necrosis.
