Whilst many of us will be familiar with the common viper's-bugloss we may not be so with plain and simple bugloss (Anchusa arvensis). The two species are not closely related with bugloss being a lungwort whilst the viper's-bugloss is an echium; both are sub-groups of the borage family, boraginacaea.
Bugloss is very much an arable weed and is far less common that it once was due to modern herbicides, indeed it is considered an obnoxious weed in some quarters and has been singled out for attack. It is often found close to the sea and I have only found it on neglected farmland at Holton Lee near the shore of Poole Harbour. Viper's-bugloss is a flower of scrubby and bare calcareous soils. Bugloss has bright blue flowers with white 'honey guides' and can be seen in flower from April to September. It is short plant rarely growing more than a foot tall.
Sadly I have not been able to find out much else about this species.Bugloss: true blue
