Plant of the Day (June 14th, 2011) - Sorbus sorbifolia (L.) A. Braun

Hi everybody. Today's “Plant of the Day” is another neophyte. Sorbaria sorbifolia (L.) A. Braun belongs to the Rosacae. In English, this plant is called “False Spirae” and in German “Sibirische Fiederspiere”

S. sorbifolia - (faded) inflorescence

At the first sight, this plant looks very similar to Sorbus aucuparia L, which I've shown you a few days ago (in fact, this similarity has given the species its Latin Name "sorbifolia", which means "Leaves like Sorbus").

It's a medium-high shrub, which can reach heights until 2 metres (or 6,6 feet). The leaves (25 centimetres long) are unpairy-pinnate and consists of 9 to 25 small leaflets. Each leaflet is lanceolate or egg-lanceolate and has a strongly serrated edge. In contrast to S. aucuparia the leaflets are not asymmetrical at their base and end in a sharp, narrow peak. In addition, their ventral side is green and bald.

The inflorescence is a simple raceme, which is between10 to 25 centimetres long . The flowers have white petals.

S. sorbifolia - leaves

Originally, this plant is home towards Siberia, North China and Korea. It is not very demanding toward its growing places. It prefers dry, well aerated soils and dislikes wet soils with too much waterlogging. So today, you can find this species also in Europe at ruderal wastelands or in bushes, where it has escaped from gardens.
