Shocking pink bell like flowers on a single stem, which stands proudly about 5cm from a single rosette of green leaves around 3-4 cm across. A small plant but very striking with it's colour and a very delicate structure. May be a marsh plant as my house is kind of near Walthamstow Marshes. Tried finding this flower in numerous books but with no joy! Hope you can help. Sarah
