When
in bud the flowers of this plant are pink or purple, becoming
a brilliant blue as they open. The leaves and stems are hairy
and very rough to the touch. Viper's bugloss prefers a dry soil
and is common on the chalk downs and on sea cliffs in many places.
It flowers from June to September, but looks its best early in
the season. As it goes to seed the stems lengthen and become untidy.
