Solanum crispum is a species of flowering plant in the family Solanaceae.

The small blue fragrant flowers, 2.5 cm in diameter, with prominent yellow ovaries, appear in clusters in summer.

The free-flowering cultivar 'Glasnevin' has gained the Royal Horticultural Society's Award of Garden Merit.

[4][5] The plant is fast-growing with a long flowering period, typically from midsummer till autumn (fall).

Requiring some protection from frost, planting it against a south- or west-facing fence or wall in full sun is recommended.
