Anchusa azurea is a species of flowering plant in the family Boraginaceae, known by the common names garden anchusa[1] and Italian bugloss (or just "bugloss"). It is a bristly perennial which may reach 1.5 meters tall and 60 centimeters wide.[2] It has straight lance-shaped leaves and petite tubular flowers about 15 millimeters across with five bright violet-blue.[3] These flowers, which typically appear May–July, are edible and attract bees.[4] This species is native to Europe and western Asia and eastern Maghreb[5] but is well-known elsewhere as a noxious weed. In Crete it is called agoglossos (Greek: αγόγλωσσος) and the locals eat the tender stems boiled, steamed or fried.
The genus name Anchusa comes from the Greek 'ankousa', which is the name of a root pigment once used for cosmetic purposes.[6]
Numerous cultivars have been selected for garden use, of which 'Loddon Royalist' has gained the Royal Horticultural Society's Award of Garden Merit.[7] Other cultivars include 'Dropmore', 'Feltham Pride', 'Little John', and 'Opal'.[8]
In the US, it's suitable for hardiness zones 3–8. It grows best in full sun with good drainage, and is drought tolerant once established.[8] It may be susceptible to leaf-miner and powdery mildew.[9]
