Lactuca muralis (Jänönsalaatti)

On of the most persistent weeds of my garden. The species is not at all common everywhere and in Finland it is restricted to the south coast. Of some reason this perennial rather demanding plant likes my garden, perhaps too much. It is fast growing and need to be weeded off in a great amount each year. The edible leaves have a funny shape, but the flowers are tiny and rather unnoticeable.
