This small to medium-sized, up to 0.5 m tall, species originates from Central Asia and colonises shady habitats, often in rich deciduous forests. The leaves are thin and flexible and spread to capture low levels of incident light. It has become naturalised in most of Europe and elsewhere. The fruits open by a virtual explosion when touched lightly, giving rise to vernacular names such as 'touch-me-not'.

I. parviflora has an unusual (false) tri-"colour" appearance. There are patches of conical cells around the entrance to the spur.
