Iochroma cyaneum 'Purple'
Iochroma cyaneum produces numerous terminal clusters of dark blue umbel-like flowers.
It is the most commonly traded species and is found in gardens with a mild climate.
The Iochroma is characterised by a low hardiness due to its tropical origin but a rapid growth.
Pruning at the end of winter gives it a more compact habit.
Watering should be regular in summer and more spaced out in winter to allow the top layer of soil to dry.
