General: The blackthorn can often be found in Germany in hedges, on the edges of forests or as pioneer bushes on lean sites. It usually grows hidden and inconspicuous as a bulky shrub together with other plants. In April / May the blackthorns can be recognized by their countless, small, white flowers. Then large parts of the landscape turn white before the leaves shoot, heralding spring. Blue frosted fruits develop from the flowers, which are edible after exposure to frost or which can also be processed into schnapps. As the name suggests, the bark and branches of the blackthorn are black and thorny. The leaves are deciduous, mostly elliptical and turn yellow in autumn.
Care as a bonsai: Blackthorns develop into incredibly beautiful bonsai. Old specimens are richly branched and the deep black bark is a great contrast to the white flowers in spring. The blue fruits in the green and later bare crown are also very ornamental. In addition, the species is very robust and adaptable. A bright location, a good supply of water and nutrients as well as regular repotting ensure healthy development. Blackthorns are frost hardy, but like all bonsai, the fresh roots are sensitive to late frost in spring.
