Swedish rowan (Sorbus intermedia)

The Sorbus intermedia is a deciduous tree perfect for medium and large gardens. Its maintenance is simple, and as in addition to a very pleasant shade during the summer, it is undoubtedly a plant to take into account.

As if that seems little to you, you should know that during the fall it becomes a magnificent color, so much so that it could well be said that it dresses up before the frosts arrive.

It is a hybrid species ( Sorbus aucuparia by another Sorbus, perhaps Sorbus torminalis or Sorbus aria ) native to southern Sweden, although it is also found in the extreme east of Denmark, extreme southwest of Finland, in the Baltic states and in the northern Poland. It is popularly known as Swedish rowan, and it grows to a height of between 10 and 20 meters, with a trunk diameter of up to 60cm.

The leaves are green on the top and hairy on the underside, and are 7 to 12cm long and 5 to 7cm wide. They are made up of 4 to 7 lobes, being wider in the middle, and rounded at the apex. During autumn they turn yellowish to grayish brown before falling.

The flowers have five white petals, are about 15-20mm in diameter, and bloom in early spring. The fruit is an oval pommel 15mm long by 10mm wide, which acquires a reddish or orange-reddish color when it ripens in autumn.
