Pride of Madeira.(Echium candicans)
Echium candicans is cultivated in the horticulture trade and widely available throughout the world as an ornamental plant for traditional and drought tolerant water conserving gardens. It is particularly suitable for coastal planting, and is a popular ornamental in coastal California. With a minimum temperature requirement of 5–7 °C (41–45 °F), in frost-prone areas it needs some winter protection. It has gained the Royal Horticultural Society's Award of Garden Merit.
In New Zealand it is a common garden escape onto road-side verges and shingle banks throughout the drier parts of the two principal islands.
In the state of Victoria, Australia, it is considered to be a high weed risk and an alert has been posted by the Department of Primary Industries. Original public domain image from Flickr
