Lycianthes rantonnetii
(Blue Potato Bush)
Source
Lycianthes rantonnetii is a species of flowering shrub in the family Solanaceae. Cultivated as ornamental the world over, you might deem it boring and decide to pass it over. But you'd be wrong.
The blue potato bush is one of about 150 species in the genus Lycianthes, which are found mostly in tropical regions of the Americas, with others in the Asia-Pacific region.

The species is named after Barthélémy Victor Rantonnet, a 19th-century French horticulturalist, who thought at first that it should be lumped in with the nightshades (Solanum) - the same genus as potatoes, hence the frumpy common name: Blue Potato Bush

You can train it into a little tree, or let it be shrubby. It's easy to prune an doesn't care much when you do it. The flowers don't have a scent but aside from that it's a great little plant that handles all sorts of abuse cheerfully.

Oh, and boring? More like dangerous. Like most nightshades all parts of this plant are poisonous so keep your kids and dogs out of the flower beds people. A source of psychoactive alkaloids, they will cause a nasty upset stomach and worse.
