Saponaria officinalis

Saponaria officinalis or Soapwort has a long list of names it is commonly called, which I will include at the bottom of this page. Its Latin name also is derived from ‘Sapo’ or Soap, which refers to saponin found in the roots. This is a toxic substance but produce lather when mixed with water.

Saponaria officinalis is native to Europe, Asia, and Western Siberia, but it can be found in North America where it seems to be invasive. It is a rhizomatous perennial, and part of the Caryophyllaceae family of plants. It is clump-forming with upright stems.

Saponaria officinalis grows to be 70cm or 2.5ft. It has opposite leaves on the stems which are unbranched. Saponaria officinalis is a rhizomatous perennial. It flowers in the summer.

It produces pink shades of flowers that open in the evening and have had a life of three days. They are fragrant and more scented at night. They release pollen on the second night and stigma develops to its final position on the third night.

How to grow Saponaria officinalis:

Grow Saponaria officinalis in the sun. Plant it in average to moderately fertile and well-drained soil which is slightly alkaline. It will tolerate poor soil. Propagate by seed or division. No pruning is necessary. Watch out for slugs and snails otherwise, it is disease-free. The nectar attracts butterflies and bees, but it is deer resistant. Deadhead the flowers for a longer blooming season.

About Online Flower Garden & Dino

I am a flower enthusiast and a gardener at heart. Ever since childhood I loved reading about plants and started gardening at an early age. First by helping my father in the garden and later managing a large garden myself in my teen years. I planted and cared for a large number of plants, flowers, and trees both outdoors and in a greenhouse. To this day I enjoy visiting gardens and parks and learning about new and old specimens and varieties of plants.
