Lycianthes rantonnetii Is the Botanical name for this lovely Blue shrub or climber. It has blue/purple flowers with a yellow centre and flowers appear in masses in the warmer months. It is suited for temperate and warm climates, and grows best in a sunny position. The growth habit can be variable.... if trimmed regularly, it can retain a bushy habit, but if allowed to go wild it will be more a climber and scramble over a trellis or fence. Don't be tricked by it's name, it does not grow Potatoes , and the plant is poisonous. i took these photos in a garden in Northern Sydney.
