Silverberry or Elaeagnus argentea Pursh is a deciduous shrub with height up to 4 meters, spreading crown, silver leaves and fruits. It originates from North America and is known since 1813. Its specific features are rather slow growth and ability to grow due to abundant root system. It reproduces itself by seeds, shoots and root suckers. It tolerates transplantation and cutting well. Due to such features as decorative effect, frost resistance, unpretentiousness to soil, resistance to drought, smoke and gases, some researchers recommend to use Elaeagnus argentea Pursh in urban greening. This kind is quite common in single or multiple plantings in Moscow such as green hedges in parks and along roads. Elaeagnus argentea Pursh is not only ornamental but also a medicinal plant. |
