Saponaria or soapwort is a very old garden plant.
Saponaria officinalis 'Alba Plena' has deliciously scented double white flowers.
It is very easy to grow and is the kind of plant you take on willingly and it will stay with you throughout your gardening life. Saponaria forms a clump 40-50 cm in height and flowers from June to September.
It is very hardy and grows happily in a sunny spot in ordinary soil, which can be poor and dry.
(*) Take advantage of its drought resistance by planting it in areas of the garden that you don't water.
