Also known as Sweet Rocket, this plant has made good its escape into the wild. Originally from central Europe, this is a medium, hairy perennial which has 15-20mm violet or white, four-petalled flowers. Its leaves are narrow and pointed, the upper smaller than the lower. The flowers have a heavenly evening scent and they are borne in panicles from May to August. The seedpods are up to 10cm long and curve upwards. This lovely plant grows to about 90cm high, in hedges and waste land and it belongs to the family Brassicaceae.
I came across this plant in 2007 at Baginbun, Co Wexford where I also photographed it.
