Matthiola bicornis , the night violet, annual cultivated perennial/pot plant with inconspicuous white/purple flowers that open in the evening and then smell very intense: a surprising addition to pots and flower boxes, and ... in a frost-free greenhouse this night violet can be kept over. It flowers from June to August.
Ideal for garden lovers who enjoy sultry summer evenings.

Sow indoors in March-April or directly outdoors in May.

Native to the Mediterranean, it grows well in sunny, dry places.
