Sorbus aucuparia ; ‘Rowan/Mountain Ash’





Mountain ash is unrelated to the true ash tree.

The mountain ash is an average sized tree ranging from 8 to 10 meters. Pinnate leaves each the leaflets are around 3 to 7 cm long with serrated edges there are regularly collection 13 to 15 leaflets per leaf.



Mountain ash gets in name from being able to grow in high altitudes from up to 2000 meters above sea level and able to colonize on very little soil in the cracks of rocks and even on other tree




The importance of the Mountain ash in cities is that it is a large food source birds and this in turned spreads the mountain ashes seeds in droppings.  These berries can also be consumed by humans but are bitter and often made into jam and preserves.



The mountain ash is very hardy and can survive from very alkali to very acid soils and varying light conditioned.


This plant prefers well drained soils so grows in sandy and loamy soils but also able to grow in heavy clay soils.
