Diminutive Mediterranean annual with insignificant pale lilac four-petalled flowers that release one of the most exquisite evening fragrances of any garden plant — sweet, spicy, distinctively floral.

As a tender annual, Night-scented stock doesn't overwinter — the zone range shows where the growing season supports it. See the RHS rating for its actual cold tolerance.
Growing notes
- Sow seed scattered around evening seating areas — flowers close during the day and open at dusk, releasing powerful sweet fragrance for several hours, then close again
- The plant is visually undistinguished — sown solely for the evening scent
- Self-seeds modestly where conditions suit
- Reliably hardy from direct sown seed in cool temperate climates
