Plant of the Day (July 9th, 2011) - Calystegia sepium (L.) R. Br.

Today's “Plant of the Day” is Calystegia sepium (L.) R. Br from the Convolvulaceae. In English, this species is known as “Hedge Bindweed” and in German as “Gewöhnliche Zaunwinde”

C. sepium - habitus

This herb is a climber, that means, its stalk winds up along walls, other plants or fences. After the germination, this plant crawls across the floor, until it finds something to climb up. Then, it start winding up, by wrapping around the object multiple times. So, C. sepium can climb until heights between 1 and 5 metres (3,3 – 16,4 feet). It needs 1h 45 for one winding.

C. sepium -leaves

The stalk is bald, round and has blunt edges. The leaves are arrow-shaped with two “ears” at the base of their leaf-blade. They also has a long stalk.

The single flowers are funnel-shaped with big, white petals and tip bracts. The stamens are covered with glands.

C. sepium - habitus

This plant is native to the temperate areas of the world. So you can find it for example in the USA, Middle Europe, Asia and also Australia, Argentina and South Africa. It is very undemanding towards the soil and can be found in hedges, gardens and reeds. It's also a weed in vineyards, what can be problematic, because C. sepium is able to displace other species.
