Description

Sweet William is a biennial or short-lived perennial beloved for its clusters of bright, often bi-coloured flowers that attract pollinators. Its flowers bloom in a range of pinks, reds, whites and purples, adding a charming cottage garden feel.

It grows well in full sun to part shade and appreciates moist but well-drained soil. With moderate growth and hardy nature, Sweet William remains a popular choice for UK gardens looking for colourful summer blooms.
