How to Grow Saponaria

Saponaria are more commonly known as ‘Soapwort’ and are native to Central and Southern Europe. They are annual or perennial plants with compact clusters of pink or purple flowers that flourish throughout summer. It is suggested that these plants are best located within a low maintenance, cottage or informal garden setting amongst a wildflower or wildlife garden. Saponaria should grow to an approximate height and spread of 50cm (20”)

Saponaria are best planted in well-drained soil of chalk, sand and clay within an alkaline or neutral PH balance. Dig a hole that is as deep and a little wider than the root ball and gently lower Saponaria into place. Space plants 30cm (12”) apart and provide a thorough watering to settle the soil. They are best positioned in an area of full sun where they will thrive to optimum effect.

Although Saponaria are low maintenance, they will require regular watering during the summer, especially during periods of drought. It is recommended to deadhead your plants to encourage further blooming whilst maintaining a neat and tidy appearance. Apply a layer of mulch during the winter as this will provide an adequate level of protection to your plant from harsh frost.

It is possible to propagate Saponaria by seed or division.
