The Small Bindweed or Convolvulus is common everywhere. You find it in
the hedge-banks, on waste places and in fields, and it blooms all
summer.
This pretty plant is very well known by its pale pink or pure white
flowers. These flowers have a narrow tube which fits into the small
green sepal-cup. But round the mouth this tube widens out into a
beautiful bell, and the edges of the bell are gracefully waved all
round. Inside the flower there are curious markings like large
cream-coloured rays, and you must notice how wonderfully the flower of
the Bindweed is folded when it is in bud.
The stem of the Bindweed is very curious. It is twisted like a piece of
rope. This stem clings to any stronger plant within reach, and it will
twist itself round and round that plant till it nearly chokes it.
The leaves are dark and shiny with smooth edges, and they are shaped
like the head of an arrow. Each leaf has a short stalk of its own.
