The mountain ash tawlina is an Asian species, growing from the Urals to Kamchatka and Japan.In its natural state, it creates wide shrubs that grow with the help of underground runners.In contrast to the pure species, which does not have exceptional decorative value, the 'Sem' variety is considered one of the most attractive garden plants, as evidenced by the awards granted in Poland and abroad: a bronze medal at the Green is Life exhibition in Warsaw and a silver medal at the Dutch Plantarium fair.
Tawlina jarzębolistna 'Sem' is a hemispherical, compact shrub with colorful foliage, reaching 1 m in height. The pinnate leaves consist of a dozen or so to several dozen lanceolate leaves with serrated edges.They develop very early in spring. Young leaves are pink-orange, the older ones are yellow, and light green inside the bush.Tawlina has thick stems with an orange core inside.
The apical, youngest parts of the shoots are red, as are the petioles of the developing leaves. During vegetation, the shoots are hidden in a thicket of leaves. In June and July, small white flowers appear on the tops of the shoots, gathered in dense panicle-like inflorescences, eagerly flown by bees and butterflies.After flowering, the bushes develop small fruit in the form of dry bellows.
The rowan tawlina 'Sem' creates numerous underground runners, with which it quickly takes over the surrounding area, which is why it is a valuable soil-protective species. For this reason, it is perfect for planting on slopes, embankments, slopes and hills.The 'Sem' variety is considered to be one of the most efficiently absorbing air pollutants hazardous to human he alth in cities.
It copes well in difficult roadside and industrial conditions, while maintaining rich decorative qualities. It is perfect for planting in narrow stripes of street, housing estate and park greenery as well as in containers.Growing plants in pots effectively prevents shrubs from growing in the garden.
Requirements, cultivation and care
Tawlina is a species extremely tolerant to difficult growing conditions, tolerates both drought and very low temperatures in winter (down to -40ºC), and high summer temperatures.The shrubs grow well in average garden soils, in sunny positions or in light partial shade.
In poor light conditions (in the shade), the leaves color less.The shrubs grow he althy, are not attacked by pests or infested with diseases.They do not require any maintenance throughout the season.
