A great, little Silene for the rock garden, screes or even in a regular sunny border. The clump of fine, narrow leaves is topped up by delicate white flowers in the summer; long flowering period. It will spread if it likes the place and can be easily divided later.
Germination: best if sown in the fall, cold/moist stratification; seeds are small sow superficial.
Seeds from what goes around as ‘Starry Dreams’, I don’t see how is different from the regular species.
