Here is a wonderful though unintended juxtaposition. In the foreground is Viper's Bugloss (Echium vulgare) which grows wild in the UK. I grew one in my front garden a year or two back which self-seeded through the railings into the gaps and cracks in the pavement.
In the background there are a couple of towering specimens of Echium wildpretti. The Giant Echiums -sometimes called Giant Viper's bugloss- are native to the Canary Islands and these two are self-seeded descendants of one I planted at the front five or six years ago.
Two distinctly different though closely related species from the same family Boraginaceae have both prospered in the same way in the same urban location. Viper's Bugloss is invariably mentioned in lists of the five or ten best native plants to grow for bees and its giant relative would certainly make the non-native shortlist.
